WATER INFORMATION SYSTEMof the Czech Republ ic

Guide to applications under the responsibilityof the Ministry of Agriculture

Easily accessible information

Reliable data

Easy to navigate

Effective information service

The Ministry of Agriculture and the Ministry of the Environment, in cooperationwith other central water authorities, provide comprehensive information aboutthe waters of the Czech Republic to the general public. This data is clearlyarranged, easily accessible and easy to understand, and is not only interestingbut also very important for all the citizens of the Czech Republic. The WATERinformation system itself is already being developed, in way that focuses ontargets, and the individual applications are being gradually published in a watermanagement information portal known as WATER.

This portal is one of a number of fully expert portals dealing with watermanagement issues; its website traffic (the number of individual visitors perday) amounts to several dozen thousand visits. It should be mentioned thatthis portal is a unique system even on a European level, and this fact is evenmore significant due to the qualified approach, in particular of the RiverBoards, state enterprises, to the issues in question and their willingness tohelp promote public awareness. We trust that you will find the website aninteresting and much sought after source of information which will be,especially amidst fluctuating weather conditions and in relation to climatechange, of invaluable importance.

The portal also features a logo depicting information provided about the watersof the Czech Republic (inverted water droplets), sponsored by the stateadministration (national tricolour). From 20 March 2008 you will see the portallogotype, which is being displayed first in this publication. Welcome to theWATER Information System of the Czech Republic.

1.1. THE CZECH REPUBLICThe Czech Republic is a landlocked country in the centre of Europe, situated in thetemperate climate zone of the Northern Hemisphere. It covers an area of 78,864 km2

and has a population of almost 10.350 million. The state border is total 2,290.2 kmlong and shared with the following states: Germany (810.3 km); Austria (466.3 km);Slovakia (251.8 km) and Poland (761.8 km). Seven hundred and eighty-threekilometres of the state border are classified as a “wet border”, i.e. formed byboundary watercourses.

The Czech Republic is an important headwaters area of the European continent andin hydrological terms it can be called ”the roof of Europe“. It is situated in thewatershed of three seas: the North Sea, the Baltic Sea and the Black Sea. Practicallyall of its major watercourses drain water into neighbouring states. The water sourcesof the Czech Republic are thus almost exclusively dependent on precipitation. Thewatersheds of the North, the Baltic and the Black Seas divide the Czech Republicinto three main hydrological catchment areas: the basins of the River Elbe, the RiverOdra and the River Morava (Danube).

1.2. HYDROLOGAL SYSTEM OF THE CZECH REPUBLICThe hydrological system includes approximately 76,000 km of watercourses (with bothnatural and regulated stream channels). Under Public Notice No. 470/2001, as amendedwhich determines the register of major watercourses and the methods of carrying outactivities associated with administering them, the major watercourses total 15,536 km.They include the River Elbe (370 km), with the River Vltava (433 km), in Bohemia; theRiver Morava (272 km), with the River Dyje/Thaya (306 km), in South Moravia; and theRiver Odra (135 km), with the River Opava (131 km), in North Moravia and Silesia. Thetotal length of the minor watercourses amounts to more than 60,000 km.

The hydrological system is formed, as mentioned above, by three main hydrologicalcatchment areas: the basins of the River Elbe, the River Odra and the River Morava(Danube). In terms of the size of the Czech Republic the main river basins are, forplanning purposes, further divided into eight hydrological river basin districts(river basin districts of the Upper and Middle Elbe, the Upper Vltava River, theRiver Berounka, the Lower Vltava River, the River Ohře and the Lower Elbe, theRiver Odra, the River Morava and the River Dyje/Thaya), which are administered byfive River Boards, state enterprises: the Vltava River Board; the Ohře River Boardthe Elbe River Board); the Odra River Board and the Morava River Board.

1.3. CENTRAL WATER AUTHORITIESThe competence of the central water authorities to carry out state administrationactivities relating to the waters of the Czech Republic is regulated by theprovisions of Section 108 of Act No. 254/2001 on Water and Amendments tocertain Acts, as amended (hereinafter referred to as the ”Water Act“). The CzechRepublic has adopted a system of “shared powers” which in practice means thatthe jurisdiction of a central authority is shared by five ministries.

The area of jurisdiction of the Ministry of Agriculture as a central water authorityis defined by the Water Act as residual with regard to all acts of stateadministration for which no area of jurisdiction of any other central waterauthority has been stipulated by an exhaustive definition.

The Ministry of the Environment for instance ensures the protection of waterquantity and quality, monitoring and assessment of the status of waters, mitigatingthe impact of accidents, flood protection, meeting tasks in relation to the EC in thearea of water protection etc. The Ministry of Health carries out in co-operation withthe Ministry of the Environment the functions of a central water authority indesignating surface waters suitable for bathing. The Ministry of Transport carries outthe functions of a central water authority in terms of surface water use fornavigation. The Ministry of Defence carries out the powers of a central waterauthority in matters constituting the jurisdiction of military districts. Watermanagement administration in military districts, carried out in these territorial unitsby the military district authorities, is usually in connection with a specific situation.

1.4. WATERCOURSE ADMINISTRATORS UNDER THE RESPONSIBILITYOF THE MINISTRY OF AGRIGULTUREWatercourse administrators under the jurisdiction of the Ministry of Agriculture areresponsible for the administration of more than 94.5% of the length of allwatercourses in the Czech Republic. The administration of approximately of 5.5%watercourses is shared by the Ministry of Defence, the national park administrationbodies or, as the case may be, by natural persons and legal entities. Watercoursesin the Czech Republic are divided into major and minor/small watercourses. Theexpert administration of watercourses is carried out under the provisions ofSection 47 of the Water Act.

Major watercourses, with a total length of 15,536 km, and a minor part of specifiedsmall watercourses, with a total length of 1,380 km, are administered by RiverBoards, state enterprises, i.e. the Vltava River Board, state enterprise (4,761 km ofmajor watercourses), the Ohře River Board, state enterprise (2,290 km of majorwatercourses), the Elbe River Board, state enterprise (3,560 km of majorwatercourses), the Odra River Board, state enterprise (1,111 km of majorwatercourses) and the Morava River Board, state enterprise (3,813 km of majorwatercourses). The specific account of major watercourses is stated in Public NoticeNo. 470/2001, as amended, which lays down the list of major watercourses and themethod of carrying out activities associated with administering them.

The activities of River Boards, state enterprises, are, in addition to Act No.305/2000 on River Basins, specified by the subject of business activity, recorded inthe Commercial Register and in the Memorandum of Association. The basic role ofthe state enterprise is to carry out the duties of a river basin administrator, anadministrator of the major and the specified minor watercourses; operating andmaintaining state-owned hydraulic structures that the state-owned company isauthorised to manage; and inexercising rights and carrying out other duties andactivities entrusted to the state enterprise. All the activities of the River Boards,state enterprises, focus on the protection and inspection of the quantity andquality of surface waters and groundwater; conservation of the environment wherewater occurs; maintenance and operation of water management and hydropowerfacilities and waterways; economical and efficient use of waters, general protectionagainst the detrimental effects of water; and establishing conditions for generalwater use and effective use of tangible and intangible assets. The state-ownedcompany acts within the scope of its activities and in accordance with legalregulations, on its own behalf and upon its own responsibility.

11

Minor/small watercourses are administered under the provisions of Section 48 ofthe Water Act. The majority of minor/small watercourses are administered by theAgricultural Water Management Authority (35,700 km) and by Forests of the CzechRepublic, state enterprise (19,536 km). Minor/small watercourses are administeredthrough delegation by the Ministry of Agriculture under the provisions of Section48, Subsection 2 of the Water Act.

2.1. INFORMATION ABOUT THE PROJECTThe WATER information system of the Czech Republic was officially launched in 2005upon joint approval of the key documents (project aims, basic communication rules,joint objectives, graphic design manual and schedule of implementation of projecttasks). The main impetus for implementing the project was the provisions of Section22, Subsections 3 and 4 of the Water Act, which impose on the Ministry of Agricultureand the Ministry of the Environment the obligation to administer and operate therespective public administration information systems for keeping individual recordsunder the provisions of Section 21, Subsection 2, Letter c) of the Water Act.

To this end, the Ministry of Agriculture, in co-operation with the Ministry of theEnvironment, produced Public Notice No. 391/2004 on the scope of data contained inrecords of surface water and groundwater status and on the method of processing,storing and presenting this data in public administration information systems. ThePublic Notice specifies in detail an overview of all records under the responsibility ofthe aforementioned ministries and lists all data registered under this Public Notice.The data is processed, presented and stored in the public administration informationsystem. In addition to the responsibilities of the respective ministries for the aboverecords, the Public Notice includes the direct responsibility of professionally qualifiedentities (under the jurisdiction of the individual water authorities) responsible forcollecting and recording data in the scope of their operation information systems. Theprofessionally qualified entities under the responsibility of the Ministry of Agricultureconsist of the following bodies: River Boards, state enterprises, the Agricultural WaterManagement Authority and Forests of the Czech Republic, state enterprise. As regardsthe area of responsibility of the Ministry of the Environment, these entities comprisethe following bodies: the Czech Hydrometeorological Institute and the T.G. MasarykWater Management Research Institute, public research institution.

2.2. MAIN OBJECTIVES OF THE PROJECTThe main objective of the interdepartmental project WATER Information System ofthe Czech Republic is the uniform presentation of water-related information, whichis the responsibility of all central water authorities of the Czech Republic. Itprovides both the expert and lay public with a comprehensive source oftrustworthy and relevant information about waters and serves as a basis fordecision making and education, and as a means of promoting general awareness.The information is provided effectively in a unified manner, from one place. Thisinterdepartmental project is co-ordinated by the Ministry of the Interior, whichalso provides inter alia the basic web hosting services of the portal.

At present, the Ministry of Agriculture and the Ministry of the Environment havea legal obligation to publish selected data relating to the water sector, in thepublic administration information system. The other central water authoritiesinvolved (the Ministry of Defence, the Ministry of Health and the Ministry ofTransport) currently do not have this duty. Their active co-operation is, however,necessary to ensure the proper function of the uniform rules of the project.Obviously, if there is a need for the ministries to publish their data they have theoption of presenting the information as part of this project at any time.

To independently present information on the division of competences in thewater sector in the Czech Republic

To provide credible and relevant information in the water sector

To present information in one place

To present information about the water sector in a comprehensive manner,stating the data source

To present information in a single form

To help improve the carrying out state administration functions in watermanagement

To build simple and effective open system

2.3. PROJECT ORGANISATIONImplementation of the interdepartmental project, called the WATER InformationSystem of the Czech Republic is scheduled for the 2005–2010 period. The areacovered by this project includes individual project tasks (records), which are underthe responsibility of the accountable ministries. They are obliged to present therespective data on behalf of these departments as part of the public administrationinformation system (see the provisions of Section 21 of the Water Act).

The ministries involved, i.e. the Ministry of Agriculture and the Ministry of theEnvironment, implement and finance their respective project areas, based ondocuments approved by the Project Steering Committee and at the consultativemeetings of the management of the ministries. For this reason, a schedule for theimplementation of individual project tasks in the calendar year in question issubmitted to the Ministry of Agriculture annually. The total estimate of fundsnecessary for creating the records under the responsibility of the Ministry ofAgriculture in the years 2005–2010 amounts in total to CZK 5 million, excluding VAT.To ensure the successful implementation of this interdepartmental project a three-tierorganisational structure was established, formed by the appointed representatives ofall central water authorities and the Ministry of the Interior, in its capacity as projectco-ordinator.

Project teams are set up consisting of representatives of the individual departmental organisations dealing with their own

issues concerning the approved project tasks. The final setup of the project team is determined by the project manager.

2.4. WATER MANAGEMENT INFORMATION PORTAL – WATERThe individual applications are gradually published on the water managementinformation portal – WATER (www.voda.gov.cz), which is the output of theinterdepartmental project. The project administrators are the Ministry ofAgriculture and the Ministry of the Environment, in co-operation with the othercentral water authorities (the Ministry of Defence, the Ministry of Transport andthe Ministry of Health) and in coordination with the Ministry of the Interior. Theindividual ministries use this website to provide interesting information relating tothe water sector in the Czech Republic.

The basic idea of the website design is based on the fact that the system in questionis decentralised (distributed), with individual applications (records) being operated bythe entities which have produced the data. These applications are basicallysub-applications using the central services of the access portal, which serves asa “signpost“ to the respective databases. The ministries thus use the uniform,well-arranged and easily accessible applications to present the general public withcredible information about Czech waters and in this way contribute to better andearlier awareness of the public as well as to meeting their legislative obligations.With regard to the scope and presentation of the individual applications (records)and navigating them, this system is absolutely unique, even by European standards.

The obligatory records of the WATER Information System of the Czech Republic are alsoavailable for downloading. Visitors to the Water management information portal –WATER are free to view selected records containing territory–related information ona detailed digital map. In the final stage the project should enable the individualrecords to be shared as part of other public administration information systems, thusallowing their operators to use the website map services to include certain parts of theWATER Information System of the Czech Republic in their applications in a differentcontext. They can therefore use such parts without the need to update and copy them.

The main structure of the Water Management Information portal – WATER web siteis based on three main bookmarks which also comprehensively illustrate thearrangement of this publication. These bookmarks are:

• Current information• Records of the WATER Information System of the Czech Republic• Information about the project

3. Current Information

23

The current information includes ”above-standard” data, currently provided by theriver basin administrators, i.e. the River Boards, state enterprises, and thepresentation of which is not based on any of the legal regulations of the CzechRepublic currently in force.

Flood situations as well as dry periods constitute the largest disaster threats in theCzech Republic. This fact is due to its location on the continental and global scale.Floods cannot be prevented; only their impact on the lives of citizens and theirproperty can be mitigated. The role of the Ministry of Agriculture as the founder ofthe River Boards, state enterprises, is to act as an intermediary for the generalpublic in the presentation of data collected by the expert watercourseadministrators, who monitor the data for their own day-to-day work.

To this end they use up-to-date information which allows the public to have accessto continuous information about water level stages and flow rates on watercourses.In flood situations this data allows everyone to build up a picture of the situationwhich is developing on individual watercourses, find out how fast the flood wave istravelling and how the water level stages on watercourses are increasing or falling.Everything is up-to-date because the data is updated every thirty minutes duringthe floods. The degree of flood activity is also indicated.

Newly presented information about the current water level stage in the respectivereservoir is very important for potential flood wave storage when the flow rates inwatercourses are increasing. The current status of the particular capacities inreservoirs is indicated by colour codes, and the presentation of their distribution,including detailed descriptive data and explanatory notes is graphically very wellarranged. The current information about water quantity in the reservoir including thevalues of both the inflow and the simultaneous runoff volumes is thus available inthirty minute intervals, not only in flood situations. In this way the public hasaccess to transparent and complete information regarding operations of majorreservoirs.

Other information also published includes data on the volume of precipitationaccumulated during the last 24-hour period and measured in one-hour intervals, atalmost 180 sites in the Czech Republic. This data is used to inform the public aboutthe level of water saturation in the individual catchment area and its potential

24

impact on the increase in water levels in watercourses. This information is providedby the precipitation gauge stations operated by the Czech HydrometeorologicalInstitute and by the River Boards, state enterprises.

An integral part of the current information is water quality in selected reservoirs,allowing the monitoring in reservoirs of the quality of surface waters with regard totheir trophism. An important indicator defining the quality of water in reservoirs iswater transparency, which It indicates the clarity of water stored in a reservoir ata given moment. As well as details temperature and chlorophyl value, the publicreceives information having a significant impact on the frequency of recreationalvisits to reservoirs.

Apart from the account of the current information there is also an applicationdealing with the technical records of watercourse features and properties. Thisapplication is a system of extensive technical information about structures andfeatures on watercourses in relation to where they are located on a watercourse.This application is used to make public the basic information regarding dams,gauging stations, weirs, surface water and groundwater abstraction sites,wastewater discharge sites, reservoirs and water quality control hydrometricprofiles.

25

3.1. WATER LEVEL STAGES AND FLOW RATES ON WATERCOURSESWater level stages and flow rates on watercourses are based on the selected profilesof stream flow gauging stations in the national monitoring network operated by theCzech Hydrometeorological Institute and of the complementary hydrometric profilesoperated by River Boards, state enterprises. These stations measure the water levelstage (in cm) and the respective derived flow rate (in m3.s-1).

The presentation shows the degree of flood activity. There are three levels of activity:Flood activity degree I – state of alert; Flood activity degree II – state of danger andFlood activity degree III – state of emergency. River locations for reports of the floodforecasting and warning service (A category profiles) are situated at the sites of thestream flow gauging stations operated by the Czech Hydrometeorological Institute orby watercourse administrators. The measuring stations are fully automated. Some ofthe reporting river sites (B category profiles) are also located at the sites of theexisting stream flow gauging stations. All of these reporting river sites (profiles) havesufficient technical equipment, i.e. with a staff gauge installed (in most stationstogether with graphical or digital recording equipment) and a discharge/station ratingcurve specified for each profile. Hydrological observations in these stations are mainlyconducted by volunteer observers of the Czech Hydrometeorological Institute and toa smaller extent by operation personnel of the River Boards, state enterprises. Auxiliaryreporting river sites (C category profiles) are operated by municipalities, for a specificpurpose, or by the owners of the property exposed to the flood threat, and are of localimportance. They can form the basis of local flood warning systems and thus warn thepopulation, especially of the course of storm floods on small watercourses.An integral part of this application is also the presentation of another hydrologicalextreme, i.e. the indicator of “drought“ which is – unlike floods – characterised bya stream flow recession below a certain limit. In the application it is characterised bya mean daily discharge achieved or exceeded 355 days a year on average.

Monitored indicators:• Water level stage (cm)• Stream flow rate (m3.s-1)• Flood activity degrees• Drought indicator Q355 (m3.s-1)

Main benefits:• Timely information about flood or drought threat• Regular monitoring and updating• Select language option

3.2. WATER LEVELS IN RESERVOIRSThe Water levels in Reservoirs application presents information in form of thequantities measured in the reservoirs administered by the River Boards, stateenterprises, updated at thirty minute intervals.

The values, which are regularly measured and recorded at the 101 reservoirs on theCzech Republic administered by the River Boards, state enterprise, include waterlevels, air temperature and precipitation amount. In addition, for some of thereservoirs the application presents the values reflecting the inflow of water intothe reservoir, or, as the case may be the water runoff from a reservoir, which wereeither measured, or derived from a particular hydrological balance.

Clearly arranged and up-to-the minute information about the current water level inreservoirs is presented through differentiating the individual areas in the reservoir.The water level in reservoirs may thus be at the level corresponding to theusable/effective storage capacity, the manageable flood storage capacity or mayeven exceed the maximum water level. For each of the reservoirs besides this datathere is a clearly arranged diagrammatic chart showing the distribution of theindividual areas in the water reservoirreservoir.

Monitored indicators:• Water level in the reservoir (in m above mean sea level)• Volume of water in the reservoir (mill. m3)• Water inflow and runoff (m3.s-1)• Precipitation (mm)• Air temperature (°C)

Main benefits:• Timely information about flood threat• Regular monitoring and updating• Clearly arranged graphic form• Comprehensive information about operation on large reservoirs which the River

3.3. PRECIPITATIONCurrent information about one-hour precipitation amounts and air temperatures isgenerated by precipitation gauge stations in the national monitoring networkoperated by the Czech Hydrometeorological Institute, in climate stations and onhydraulic structures administered by the River Boards, state enterprises. The data isreceived continuously from almost 180 sites in the Czech Republic.

This application makes it possible to obtain an overview of one hour precipitationamounts measured during the last 24 hours and daily precipitation amounts measuredduring the last seven days from the automated precipitation gauge stations. Whentemperatures are above freezing point, the automated precipitation gauge stationnetwork shows the rainfall amount for the previous hour. The temperatures are“negative“ when falling snow is melting, and the apparatus measures the amount ofwater it contains. In a standard situation the data is updated every hour; in a floodthreat situation and during floods the updating frequency is higher.

Precipitation measurement in automated precipitation gauge stations was includedin the monitoring and control system used by the water management operationalcentres of the River Boards, state enterprises, with the specific aim of improvingthe forecasts of the subsequent flow rate evolution, in particular on the upperstretches of watercourses when using the HYDROG or AQUALOG forecasting rainfall-runoff mathematical model.

Monitored indicators:• One hour precipitation amounts during the last 24 hours (mm)• Daily precipitation amounts during the last seven days (mm)• Air temperature (°C)

Main benefits:• Timely information about precipitation amounts and their subsequent impact on

flood threats• Regular monitoring and updating• In a ”negative“ temperature situation the apparatus measures the amount of

Monitoring water transparency and other important indicatorsaffecting water quality in reservoirs (e.g. chlorophyl-a) is carried out only duringthe growing season, i.e. from April to October each year.Water temperature is measured all the year round, every day at 7 a.m. severalcentimetres below water level, near the dam. It is an appropriate indicator of boththe ice occurrence and ice drift, and in reservoirs suitable for recreation it indicatesbathing conditions. It is measured manually by a calibrated thermometer. The watertransparency is measured by means of a Secchi disk once or twice a week at thesame time of day and subject to local conditions, either from a boat or anothersuitable place close to the water level. Samples for measuring chlorophyl-a aretaken in the specified place (mainly the location specified for measuring watertemperature), using a special sampling device, once a month. The identifiedconcentration value of this substance in water allows high accuracy evaluation ofthe level of algae and cyanobacteria presence at the measurement site.For selected reservoirs a number of indicators are presented using of ReViewersoftware, allowing evaluation of the presented data in colour and comparing it withthe previous calendar year. The indication of substance distribution is derived froma determination carried out on vertical lines which are plotted at the reservoirs ona permanent basis. The position of these vertical lines is marked with a yellow ringin the reservoir diagrams. By activating this symbol on the screen the distributionof selected parameter values in the given cross section is displayed. Activation ofany point on the water level displays in the chart the spatial distribution of theselected parameter in the longitudinal profile of the reservoir.

Monitored indicators:• Temperature (°C)• Transparency (m)• Chlorophyl-a (µg.l-1)• pH value, dissolved oxygen etc.

Main benefits:• Monitoring on public water supply reservoirs and reservoirs used for recreation

and fishing• Regular monitoring and updating• User-friendly graphical evaluation

3.5. CENTRAL TECHNICAL REGISTRY OF WATERCOURSE FEATURES AND PROPERTIESThe register is a system of extensive and wide-ranging technical information aboutstructures and features on watercourses in terms of where the structures arelocated.

The technical register uses the records in the basic watercourse register includingthe watercourse parts and stretches according to their hydrological designationand the breakdown, which is based on their categorisation. The system functionsprovide a unique data link to the watercourse structural model, enabling at thesame time a link to the mapping data. For this reason the system currently makesuse of the public administration portal mapping services.

All the technical information about the structures and features on watercoursespublished on the portal is jointly registered by all of the five River Boards, stateenterprises. The presentation currently includes only selected features, which arepublished on the basis of an agreement with the representatives of all the RiverBoards, state enterprises. These selected features currently are: dams,measuring/gauging stations, weirs, surface water and groundwater abstractionsites, wastewater discharge sites, reservoirs and water quality control hydrometricprofiles.

Monitored indicators:• Uniform standard for River Boards, state enterprises• Basic information about selected structures and features on watercourses

Main benefits:• Option of selecting structures and features by the respective watercourse and

river kilometres• Option of selecting and view the technical register data based on competence of

the River Boards, state enterprises• Option of browsing the structural model of watercourses• Regular updating

3.6. MOBILE INTERNETMobile equipment offers a unique possibility of continuous information aboutimportant up-to-date events literally anywhere and at any time. If you need tocurrent information quickly about the quantity of water in our watercourses andreservoirs and you do not have a computer with an Internet connection close athand, you can access not only this but also other information through mobileequipment (mobile phone, handheld devices etc.) supporting WAP technology.

For this very reason the Ministry of Agriculture, in co-operation with the River Boards,state enterprises, ensures the presentation of the most important information also bymeans of this technology. Therefore, the general public can currently find on therelevant WAP sites current information about the volume of water and flow rate inwatercourses, water level stage in reservoirs and precipitation volume, including themost important contacts to the particular River Boardstate enterprise.

This service is of invaluable significance especially during floods, when thecitizens, mayors of municipalities or as the case may be the members of theindividual flood protection commissions can monitor directly in the field how theflood situation is evolving.

4. Records of the Information system WATER in the Czech Republic

49

The records of the WATER Information System in the Czech Republic comprisea detailed set of “mandatory” data based on the provisions of the Water Act. Throughthe provisions of Sections 21 and 22 the Act imposes on the Ministry of Agricultureand the Ministry of the Environment the duty to keep appropriate records as a part ofthe public administration information system according to the particulars resultingfrom Act No. 365/2000 on Public Administration Information Systems, as amended.

To this end, in 2004 the Ministry of Agriculture, in co-operation with the Ministryof the Environment, issued Public Notice No. 391/2004 on the scope of datacontained in records on surface water and groundwater status and on the methodof processing, storing and presenting this data in public administrationinformation systems. The Public Notice specifies in detail an overview of all therecords under the responsibility of the above ministries and provides an account ofall data registered under this Public Notice, which is processed, presented andstored in the public administration information system. In addition to theresponsibilities of the respective ministries for the above records, the Public Noticeincludes also the direct responsibility of the relevant qualified entities (under thejurisdiction of the individual water authorities) responsible for collection andrecords of data in the scope of their operation information systems.

The provisions of Section 19 of the Water Act at the same time stipulate thatwater authorities are obliged to store in the public administration informationsystem selected data from the records they keep on their decisions, as specified byPublic Notice No. 7/2003 on Water Management Records, as amended, and totransfer this data to the Ministry of Agriculture. The records of the final andconclusive administrative decisions issued by water authorities are also included inthe content of this bookmark.

Thanks to the information contained in this bookmark, which is presented by theMinistry of Agriculture, the public can have an overview of the responsibilities forwatercourse management and maintenance, and an overview of reservoirs andsurface water quality, permitted abstractions and discharges, records of the riverbasin districts, sources of drinking water, land improvements and reclamation orwater management records. The information provided includes well-arranged, easilyaccessible and comprehensible data which is interesting and very important for allcitizens of the Czech Republic.

4.1. WATERCOURSE REGISTERThe watercourse register comprises sub-records kept by the individual watercourseadministrators – the River Boards, state enterprise the Agricultural WaterManagement Authority (including data concerning natural persons and legalentities), Forests of the Czech Republic, state enterprise, the National Parksadministration bodies and the Ministry of Defence, which is responsible for militarydistricts. The watercourse layer, the “Central Watercourse Register/Records (CEVT)”,is the basic structural and linking register, and is used for additional territorial linksto features of other records and for subsequent updating watercourse layers in therelated public administration information systems.In the first stage of the process of compiling this register the individual watercourseadministrators processed and updated the original register produced by the T.G.Masaryk Water Management Research Institute, a public research institution, usingthe Basic Water Management Map of the Czech Republic, on a 1:50,000 scale. Thesubject matter of the modifications made by the watercourse administrators at thisstage of work was to check the administration and management issues and to adda unique identifier number to the respective watercourse (CEVT IDVT). In the year2007, this data was matched with the National Map of the Czech Republic, ona 1:10,000 scale (ZABAGED), for updating and specifying the registered data in moredetailed form, including the transfer and implementation of the watercourse layer,on a scale of 1:10,000, in the operation information systems of all the River Boards,state enterprises. Identifying watercourses administered and managed by the RiverBoards, state enterprises, was also an integral part of these activities.At present the WATER information system in the Czech Republic comprises both theoriginal records of watercourses, on a scale of 1:50,000, and the newly compiledrecords, on a 1,10 000 scale (note: information about the administration is currentlypresented only for watercourses administered and managed by the River Boards,state enterprises).

Monitored indicators:• Name of the watercourse • Watercourse administrator• Identifier number of the watercourse • Territorial identification• Length of the watercourse

Main benefits:• Continuous updating of data (administration and geometry of watercourse centre lines)• Easy search based on the selected parameters (name of the watercourse, the

number of hydrological order – NHO etc.)

4.5. REGISTER OF SURFACE WATER QUALITY IN COMPLEMENTARY HYDROMETRIC PROFILES OPERATED BY RIVER BOARDS, STATE ENTERPRISESThis register is based on data on the characteristic values of surface water qualitycalculated from the values measured by river basin administrators in thecomplementary watercourse profiles.

Samples taken from all control sections are analysed to determine the general, physicaland chemical indicators of water quality. The surface water quality measurement resultsare further processed. To be able to provide general information and especially tocompare water quality at various places and different times, the quality of flowingsurface waters is classified into five water quality categories according to the Czechnational standard ČSN 75 7221 (Water quality – Classification of surface water quality):

Class I (unpolluted water) – water suitable for drinking water supply purposes, foodprocessing industry, open air swimming pools and bathing places and salmonide fishfarming. Unpolluted water is of a large landscape enhancement value.Class II (slightly polluted water) – suitable for drinking water supply purposes, fishfarming, water sports and industry. Slightly polluted water is of a good landscapeenhancement value.Class III (polluted water) – water suitable only for water supply to industry and onlyappropriate for drinking water supply if no other more suitable source is available.Polluted water is only of a low landscape enhancement value.Class IV (heavily polluted water) – as a rule water only for certain limited purposes.Class V (very heavily polluted water) – as a rule, water unsuitable for any purpose.

Monitored indicators:• Water temperature (°C) • Ammonia and nitrate nitrogen (mg.l-1)• Water reaction • Total phosphorus (mg.l-1)• Electrolytic conductivity (mS.m-1)• Biological oxygen demand – BOD5 (mg.l-1)• Chemical oxygen demand by dichromate – CODcr (mg.l-1)

Main benefits:• Territorial identification of hydrometric profiles used for quality monitoring of

surface water • The data is stored for the previous calendar year by June 30 of the relevant

calendar year at the latest • Classification of waters in water quality classes according to the relevant standard

4.6. REGISTER OF SURFACE WATER QUALITY IN THE HYDROMETRIC PROFILESOPERATED BY THE AGRICULTURAL WATER MANAGEMENT AUTHORITYThis register is based on the data on characteristic values of surface water qualityindicators, which are calculated from the values measured in the hydrometricprofiles of surface water status and quality monitoring, operated by theAgricultural Water Management Authority on minor watercourses.

Hydrometric profiles on minor watercourses are monitored as a part of themonitoring process in the national water quality monitoring network, operated bythe Czech Hydrometeorological Institute and as part of the point pollution sourcemonitoring process.

Monitoring conducted by the Agricultural Water Management Authority keeps underreview the general physical, chemical and biological indicators allowingidentification at an early stage of minor municipal and agricultural sources ofpollution and thus a warning against the possibility of area pollution. The agentsmonitored include also selected heavy metals and some specific organic substances.

The monitoring, which should in the final instance result in constant improvementof water quality, meets the current requirements for surface water qualitymonitoring laid down by both the state administration and the EuropeanCommunity for implementation of the individual directives and regulations.

Monitored indicators:• Water temperature (°C)• Water reaction• Electrolytic conductivity (mS.m-1)• Biological oxygen demand – BOD5 (mg.l-1)• Chemical oxygen demand by dichromate – CODcr (mg.l-1)• Ammonia and nitrate nitrogen (mg.l-1)• Total phosphorus (mg.l-1)

4.9. REGISTER OF THE SURFACE WATER AND GROUNDWATER SOURCES USEDAS DRINKING WATER SOURCESThe register of surface water and groundwater sources provides information aboutall the sources which are used as sources of drinking water in the Czech Republic.The data on drinking water sources originates from the assets register on watertreatment plants both with and without water treatment technology.Under the provisions of Section 5 para 3 of Act No. 274/2001 on Public WaterSupply and Sewerage Systems and on amendment to certain laws (Water Supply andSewerage Systems Act) as amended the owners are obliged to submit selected datafrom the assets records and operational records concerning water supply networksor sewerage systems to the relevant water authorities. Under the current legalregulations the due date for handing over the data is set to February 28 each yearat the latest. Water authorities then pass on the data in accordance with theprovisions of Section 5 para 4 of the Water Supply and Sewerage Systems Act to theMinistry of Agriculture by April 30 of the calendar year at the latest. The scope andthe method of keeping the assets records are stipulated by Public Notice No. 428/2001, which implements the Water Supply and Sewerage Systems Act.Records of drinking water sources are kept within the scope of the data specifyingtheir territorial identification, their names and number code of the land registryarea, the raw water category and identification number of the water abstraction.This data is processed and transferred into the public administration informationsystem by the Ministry of Agriculture.

Monitored indicators:• Name of the source• Name and identification number of the water treatment plant• Name and code of the land registry area where the water treatment plant is located• Raw water category• Identification number of water abstraction

Main benefits:• Records on the drinking water sources which are used• Localisation of water treatment plants and sources• Well-arranged structure of surface water and groundwater sources used as drinking

water sources according to the division of the state administration in the CzechRepublic

• Information on the requirements for raw water quality including the methods oftreatment of water to drinking water standards

4.10. REGISTER OF HYDRAULIC STRUCTURES FOR WATER MANAGEMENTLAND IMPROVEMENTThe record dealing with land improvement and land reclamation is based on thedata collected by the Agricultural Water Management Authority.The Agricultural Water Management Authority is an organisational component of thestate, established by the Ministry of Agriculture for the purpose of maintaining andadministering minor (small) watercourses in agricultural landscape and the maindrainage facilities. Its nationwide area of responsibility covers five river basin districts– according to the area of responsibility of the River Boards, state enterprises.

Records on hydraulic structures designed for water management land improvementsas defined by the provisions of Section 55 of the Water Act are kept within thescope of the data specifying their territorial identification and the data laid downby the Public Notice of the Ministry of Agriculture No. 225/2002 on the detaileddetermination of structures designed for water management improvements of landand the parts thereof, the method and scope of their upkeep, with the exceptionof data on the name, surname, place of permanent residence and birth registrationnumber (personal identification number) of a natural person.

Structures designed for water management land improvements are regarded asstructures which are used for irrigation and drainage of land as well as structuresdesigned to protect the land from water erosion.

Structures designed for drainage of agricultural land are divided into the main andsubsidiary drainage facilities. In subsurface drainage systems subsidiary drainagefacilities mean lateral and main drains, drainage wells and outlets; in surfacedrainage systems they comprise drainage ditches and associated (connected)structures. Subsidiary drainage facilities are an integral part of the land in question.

Monitored indicators:• Land improvements and reclamation systems in the Czech Republic

4.11. REGISTER OF SELECTED DATA FROM EFFECTIVE DECISIONS OF WATER AUTHORITIESThese records of selected data constitute a unique database of effective decisionsissued by the water authorities and of the information selected from thesedecisions which may be used by the respective water authorities in their day-to-daypractice and by both the expert and lay public when planning their watermanagement activities. At the same time the information can also be used by otheradministrative bodies, legal entities or natural persons who need to know the scopeand the amount of water management activities which have been so far permitted.In terms of the factual content this information includes permits for water use(water abstraction, accumulation of water, discharge of wastewaters etc.), permitsfor certain activities (planting of trees or shrubs in flood plain areas to an extentwhich is affecting runoff conditions, returning a watercourse to its original channeletc.), permits for discharge of wastewaters containing especially dangerous harmfulsubstances into sewerage systems, building permits for hydraulic structures as wellas changes, cancellation and termination of permits for water use, decisions aimedat protection of water resources, territory and hydraulic structures, other measurestaken by the water authority, and occupancy permits allowing hydraulic structuresto be put into operation.The individual decisions are in these records sorted by the water authorities, interms of the monitored period and the date of their coming into force. Everydecision is specified by its reference number, its brief description, the date itcame into force and its classification according to the factual focus or subjectmatter (e.g. building permit for hydraulic structures, water use). The classificationuses eight colour tones for making it easier to use. Each decision includes as anattachment also its electronic form.

Monitored indicators:• Selected data from the effective decisions of water authorities• Decisions issued by water authorities in electronic form• Quantitative overview of the administrative duties of water authorities

Main benefits:• Support for carrying out the public administration’s duties• Data for implementation of water management objectives• Visualisation of administrative districts and the hierarchy of water authorities• Option of searching by the factual aspects of the decision• Continuous updating
