Peak Data for U.S. Geological Survey Gaging Stations, Texas Network; and Computer Program to Estimate Peak- Streamflow Frequency
By Raymond M. Slade, Jr., and William H. Asquith
Abstract
About 23,000 annual peak streamflows and about 400 historical peak streamflows exist for about 950 stations in the surface-water data- collection network of Texas. These data are pre sented on a computer diskette along with the corresponding dates, gage heights, information concerning the basin, and nature or cause of the flood. Also on the computer diskette is a U.S. Geological Survey computer program that esti mates peak-streamflow frequency based on annual and historical peak streamflow.
The computer program estimates peak streamflow for 2-, 5-, 10-, 25-, 50-, and 100-year recurrence intervals and is based on guidelines established by the Interagency Advisory Com mittee on Water Data. Explanations are presented for installing the program, and an example is pre sented with discussion of its options.
INTRODUCTION
For more than 100 years, the U.S. Geological Survey (USGS) has been monitoring and publishing streamflow data, including annual peak discharges, for streamflow-gaging stations throughout the United States. Other information associated with peak dis charges, including the date and gage height (stage) for each peak and supplemental information concerning the basin and the nature or cause of the peak, is pub lished with the peak streamflows. Collectively, this information is referred to as peak values or peak data. Peak data are of two classes: systematic, which is peak data systematically collected during the period that a gaging station has been operated; and historical, which is miscellaneous peak data outside periods of systematic
record obtained from various sources. The peak values are stored in the National Water Data Storage and Retrieval System (U.S. Geological Survey, 1979) and are published in annual data reports by the USGS.
The purpose of this report, which was prepared in cooperation with the Texas Department of Transpor tation and the Texas Natural Resource Conservation Commission, is to present on computer diskette (1) a comprehensive file of annual peak streamflows and his torical peak streamflows for stations in the surface- water data-collection network of Texas; and (2) an exe cutable version of a computer program (for IBM-com patible personal computers), including installation instructions, that estimates peak streamflow for 2-, 5-, 10-, 25-, 50-, and 100-year recurrence intervals.
The file contains about 23,000 annual peaks and 400 historical peaks for about 950 stations. Tables of supplemental information regarding the peak stream- flows and the gaging stations are in the text of this report. Included is a table of the largest historical peak streamflows (as many as eight per station) and associ ated gage heights for stations with at least 8 years of record from unregulated 1 , natural2 basins.
The computer program PEAKFQ (K.M. Flynn, U.S. Geological Survey, written commun., 1995) is based on guidelines for streamflow-frequency analysis established by the Interagency Advisory Committee on Water Data (IACWD) (1982). A summary of the princi ples of streamflow-frequency analysis associated with the computer program is in the text of this report as background information and to assist the reader in the use of program options.
An unregulated basin is defined as a basin with less than 10 percent of its drainage area controlled by reservoirs.
2 A natural basin is defined as a basin with less than 10- percent impervious cover and no human-related factors that would affect peak streamflow.
Abstract
PRINCIPLES OF PEAK-STREAMFLOW FREQUENCY
Principles of Calculation
Program PEAKFQ performs statistical analyses of annual peak streamflow following the procedure rec ommended by the IACWD. The IACWD guidelines contain a complete and definitive description of the recommended procedure.
The IACWD procedure characterizes occur rences of peak streamflows at a single site as a sequence of annual peak-streamflow events. The mag nitudes of the annual events are assumed to be indepen dent random variables following a log-Pearson Type III probability distribution (the logarithms of the peak flows generally follow a Pearson Type III distribution). This distribution defines the probability that any single annual peak will exceed a specified streamflow. Given this probability, other probabilities, such as the proba bility that a future design period will be free of exceed- ance, can be calculated by standard methods. By considering only annual events, the IACWD guidelines reduce the peak-streamflow frequency problem to the problem of estimating the log-Pearson annual probabil ity curve using the record of annual peak flows at the site. This estimated curve is what the program PEAKFQ calculates.
Peak-Streamflow Records
The peak data fall into two classes: systematic and historical. The systematic record includes all annual peaks observed in the course of one or more sys tematic gaging programs at a site. In a systematic gag ing program, the annual peak is observed (or estimated) for each year of the program. If the peak is too small to measure, an estimate of the upper bound on its magni tude is provided. This type of peak is identified in the peak values file (diskette) with an appropriate stream- flow qualification code. Streamflow qualification codes are explained later in the text. Several systematic records at one site can be combined. Gaps between dis tinct systematic record periods can be ignored, pro vided no extreme hydrologic conditions occurred during the gaps.
In contrast to the systematic record, the historical record consists of annual peaks that would not have been observed except for evidence indicating their unusual magnitude. Flood information acquired from old newspaper articles, letters, personal recollections,
and other historical sources almost invariably refers to peaks of noteworthy and hence extraordinary size. Thus, historical records, by the conditions of their col lection, form a biased and unrepresentative sample of flood experience. Despite this bias, however, the histor ical record can be used to supplement the systematic record provided that all historical peaks, which are above some historical threshold, have been docu mented.
The systematic record might contain one or more peaks for which historical information is available or which exceed the smaller historical peaks. Such peaks are called high outliers. They are used as part of the systematic record but also are treated like historical peaks in the procedure for historical record adjustment.
Systematic Record Analysis
The procedure for lACWD-recommended calcu lations done by PEAKFQ includes many steps, as illus trated in figure 1. The first step, represented by box ASP, is to calculate the statistics of the common loga rithms of the peak-streamflow values in the systematic record. At some sites, annual peaks of magnitude zero can occur; more often, the annual peak is less than or equal to some lower limit of measurement called the gage base (which could be zero). To account for this possibility, the number of peaks below the gage base is calculated in addition to the mean, the standard devia tion, and the skewness of the logarithms of the above- base systematic peaks. These procedures are indicated in figure 1 as flowchart boxes CSA and FCA. The sta tistics of the systematic peaks serve as an initial esti mate of the IACWD frequency curve and are modified as necessary by the succeeding steps.
Outlier and Historical Record Tests
The second step is to detect and make appropri ate adjustments for low outliers, high outliers, and historical peaks. The sequence of these tests and adjust ments depends on the station skew coefficient, G, cal culated in the first step. Because a relatively large skew coefficient of either sign is likely to be caused by an outlier (extreme high or low streamflow value), this possibility is checked first; and any necessary adjust ment associated with outliers of one extreme is applied before checking for outliers of the opposite extreme. If the skew coefficient is of relatively moderate size, the existence of both high and low outliers can be checked before applying any adjustments. Program PEAKFQ

detects low outliers automatically as shown in box DLO in figure 1, using the formula specified in the IACWD guidelines. High outliers also are detected automatically, in flowchart box DHH, but no adjust ment can be applied unless the user supplies necessary information about the length of the historical period. Boxes DLO and DHH merely detect the presence or absence of outliers and historical information. Flow chart box CSA, which recalculates the statistics of the above-base peaks for the historical period, performs the actual adjustments.
Historical Record Adjustment
Flowchart box CSA in figure 1 represents the recalculation of the statistics of the above-base peaks as required after the detection of outliers or historical information. It takes into account any zero flows or below-gage base peaks, low outliers, high outliers, and historical peaks that have been detected, as specified by the IACWD (1982, app. 6).
Estimation of Skew Coefficient
The skew of a frequency distribution has a tre mendous effect on the resulting shape and thus on the values of the distribution. The discussion in this section concerns the development of appropriate skew coeffi cients for the program's flood-frequency analysis. The following discussion is adapted from the IACWD (1982, p. 10-14).
A skew coefficient represents a numerical value that affects the shape of a peak-streamflow-frequency distribution curve. It is affected by watershed and cli- matologic characteristics such as drainage area, chan nel slope, basin shape, and precipitation. Station skew coefficients are derived from annual peak discharges for a station. They are sensitive to extreme peak dis charges; thus, it is difficult to obtain an accurate skew coefficient for stations with short records. Therefore, the IACWD (1982) recommends using a weighted skew coefficient with the log-Pearson Type III distribu tion, calculated by mathematically weighting the sta tion skew coefficient and a generalized skew coefficient.
The generalized skew coefficient for a site is esti mated by combining station skew information from nearby stations with similar site characteristics; the generalized skew is believed to have geographic conti nuity. The IACWD (1982, p. 10-14) presents a proce dure for estimating generalized skew coefficients. The
IACWD also presents a map depicting lines of equal skew for the United States, developed with data through 1973.
Under the assumption that the generalized skew coefficient is unbiased and independent of the station skew coefficient, the weighted skew coefficient is com puted by weighting the two coefficients in inverse pro portion to their individual mean square errors. This concept is expressed in the following equation adapted from Tasker( 1978):
GW =MSE(G) +MSEG (G)
MSE(1)
whereGW = weighted skew coefficient;
G = station skew coefficient; G = generalized skew coefficient;
MSEG = mean square error of station skew coeffi cient; and
MSE_ = mean square error of generalized skewcoefficient.
Equation 1 can be used to calculate a weighted skew coefficient regardless of the source of the gener alized skew coefficient.
PEAK DATA

Additionally, stations with urbanized basins (basins containing at least 10-percent impervious cover) are listed in table 2 (at end of report). Their peak stream- flows on the diskette are designated with a streamflow qualification code of "C."
The data on the diskette are organized for direct use in the peak-streamflow frequency computer pro gram PEAKFQ, which reads input in a fixed-format
ASCII file with three types of card images. Figure 2 pre sents an example of the N-, H-, and 3-card formats of the data on the diskette as used by PEAKFQ. The card type is specified in column 1. The N, H, and 3 cards each contain the station number in columns 3 10.

name and the name of the city with a post office closest to the station.
The H Card
The H-card format contains the latitude in col umns 17 22, the longitude in columns 23-29, and a sequence number in columns 30 and 31. Columns 36- 38 contain a code for the county name. The codes for all counties in Texas are presented in table 3 (at end of report). The hydrologic unit code, the code used to identify hydrologic areas, is in columns 41-48. The total drainage area (in square miles) is in columns 49 55. If the contributing drainage area is different from the total drainage area, the contributing drainage area is in columns 56-62. Finally, the datum of the gage, which represents the elevation above mean sea level for 0.0-foot (ft) gage height, is in columns 63-70. The water-surface elevation for the annual peak stage is therefore the sum of the datum of the gage and the annual maximum gage height. The gage datum is not known for some stations generally those with small drainage areas.
The 3 Card
The 3-card format presents annual and historical peak streamflows and associated data. The calendar year for the peak is entered in columns 17-20. A two- digit code for the month of the peak is in columns 21- 22, and the date is in columns 23-24. For example, 01 is used for January and 1005 for October 5. The stream- flow (in cubic feet per second) is in columns 25 31, the streamflow qualification codes (table 1) are in columns 32-43, and the gage height (in feet) associated with the annual peak streamflow is in columns 44-51. Finally, the water year of each peak is in columns 77 80.
Historical Peak Data
Information on historical peaks is presented in table 4 (at end of report) for selected stations in Texas. This information is presented only for stations with at least 8 years of annual peak-streamflow data from unregulated, natural basins. About 560 stations meet this criteria and are included in table 4. Selected char acteristics for these stations are presented in table 5 (at end of report), and the locations of the stations are pre sented in figure 3. Locations of stations with less than 8 years of annual peak-streamflow data from unregu lated, natural basins are presented in figure 4. Histori cal peaks for stations not in table 4 (those with less than
8 years of record from unregulated, natural basins) are in the peak values file (diskette).
Historical information in table 4 includes dates and peak gage heights and peak streamflows, if avail able. Also, when available, the historical significance is presented for all historical peaks. The significance is expressed as the "highest since" or "highest since at least" for a specified peak. An "S" identifies a date as being a "highest since" date rather than a "highest since at least" date. This information typically originates from residents living near the gaging stations. Most of the stations are in rural areas, and searches were made near most stations to locate and interview residents with long-term information regarding floods. Rem nants of historical peak stages (debris left by peak stages) were located and surveyed to the datum of the station to establish a historical peak gage height. When possible, peak streamflows associated with historical peak gage heights were estimated.
Wherever a date for the "highest since" or the "highest since at least" appears in table 4, peaks are presented in descending order of the streamflow for the largest peak streamflows since that date. For some sta tions, more than four of the largest peaks are known. For those stations, the remaining largest peaks are pre sented in the "Additional information" section of table 4. Gage heights are used to rank the peaks when streamflows are not available. If neither gage heights nor peaks are available, entry in the table is based on information from long-term residents. An "E" between the gage height and the streamflow signifies that the sequence order between two or more peak streamflows cannot be determined. A "T" between the gage height and the streamflow signifies that the gage height or the streamflow is identical to another gage height or streamflow. Finally, for some stations historical peaks can be attributed only to a decade of occurrence rather than to a year. These peaks are identified with a "D."
Historical peak streamflows can greatly affect the streamflows calculated by PEAKFQ. When histor ical peak streamflows are available, along with a date for the "highest since" or "highest since at least," that information can be used in PEAKFQ to make adjust ments to the streamflows calculated by PEAKFQ, which affect the computed estimate of peak-stream- flow frequency. An example involving such adjust ments is presented in the following section.

INSTALLATION AND EXAMPLE OF COMPUTER PROGRAM (PEAKFQ) TO ESTIMATE PEAK-STREAMFLOW FREQUENCY
Program Installation
The diskette contains an ASCII file (READ.ME) that explains the procedure for installing the program PEAKFQ. The program INSTALL.EXE on the diskette contains the routines that install PEAKFQ. Follow the instructions contained in the READ.ME file to install and execute the program. Questions concerning the operation, options, and output of the program, as well as identification of bugs in the program, can be directed to:
Office of Surface Water, WRD U.S. Geological Survey MS 415, National Center Reston, VA 22092
Program Example
This section describes the steps to produce a basic statistical analysis of peak-streamflow frequency using PEAKFQ and discusses several of its more commonly encountered options. Following is an example of how to use PEAKFQ to estimate peak-streamflow frequency for a single station. The N, H, and selected 3 cards are shown in figure 2 for station 08150700, Llano River near Mason, Texas. The data file, TEXPEAKS.TXT, must be uncompressed on hard disk as described in the READ.ME file before the example can be followed.
Stepl
After starting the PEAKFQ program, select the INPUT menu, using the arrow keys and the "F2" key, and select the ASCII input option by pressing "F2." Now type the path name to TEXPEAKS.TXT and return. At the top of the screen choose "S," and the "All" will be toggled to "Some." Select "Enter." In the first blank cell enter the station number "08150700" and press "F2." This returns the program to the opening screen.
Step 2
Now select the OUTPUT menu. On the screen select the "File" option. Here the output file name will be specified. For this example type "VLLANO.OUT"
and press "F2." Then select the "Return" option. This returns the program to the opening screen.
StepS
Now the analysis procedure can begin. Select the "START" menu using the arrow keys and press "F2." This menu allows the user to adjust the parameters con trolling the type of analysis.
The "begin year" and "end year" options allow the user to choose specific periods of analysis for the sta tion. The default values represent the entire systematic record without regard to regulation (code 6 peaks) or urbanization (code C peaks). If the analysis is desired for only the unregulated part of record, then the "end year" needs to be changed to the last year of unregulated record. Likewise, if analysis is only desired for the reg ulated part of record, then the "begin year" needs to be changed to the first year of regulation. Also, when any regulated record is to be used, the option "Allow urban/reg peaks" needs to be changed to "Yes."
Next, move the cursor using the arrow keys down to the "Length of historic period" option. The length of the historical period is found by consulting table 4 for the "highest since" or "highest since at least." For sta tion 08150700 this date is 1875. For stations without historical peaks, leave the "Length of historic period" as "0.0"; only the systematic record will be analyzed. Now consult table 5 or the peak values file for the ending date of the station. Table 5 shows that this station was active through at least 1993; therefore, for this station, the length of the historical period is 1993 minus 1875 plus 1 year, which is 119 years. Type " 119" into the "Length of historic period" option and move the cursor to the "Hi-outlier threshold" option. This threshold allows for the IACWD historical adjustment. For this station, the four highest peak streamflows are known. The fourth highest peak is 218,000 cubic feet per second (ft3/s). Enter a peak value just less than 218,000 into the "Hi- outlier threshold" option type "217999." Note that entering "0.0" for "Hi-outlier threshold" will cause the program to ignore the historical record length regardless of whether or not the length of historical record was greater than the systematic record and will cause the lACWD-calculated high-outlier threshold to be used.
Now, the "skew calculation option" can be selected. Three options are available: "WTD," the weighted skew coefficient based on the generalized and station skew coefficients (default); "GEN," the general ized skew coefficient from the generalized skew map
INSTALLATION AND EXAMPLE OF COMPUTER PROGRAM (PEAKFQ) TO ESTIMATE PEAK-STREAMFLOW FREQUENCY
(Interagency Advisory Committee on Water Data, 1982); or "STA," the station skew coefficient calcu lated from only the systematic record with appropriate adjustments for high and low outliers, if applicable. The weighted skew coefficient generally is preferred. For station 08150700, use the weighted skew coeffi cient option. The program defaults to the generalized skew coefficient based on the station's latitude and lon gitude. Another generalized skew coefficient can be selected to replace the default value. A recent investi gation of generalized skew coefficients has been done for Texas (L.J. Judd, U.S. Geological Survey, written commun., 1994). That study updates the generalized skew coefficients, which are based on data through 1973; much data have been collected since then. For station 08150700, the generalized skew coefficient from the recent investigation is -0.051 and the standard error of this coefficient is 0.35. Move the cursor to "Generalized skew" and type "-0.051"; then move the cursor to the "Std error of gen. skew" and type "0.35."
Finally, the "Lo-outlier threshold" can be selected. Leaving the "Lo-outlier threshold" equal to "0.0" will cause the lACWD-calculated low-outlier threshold to be used. However, Asquith and others (1995) demonstrate that the IACWD procedure for low-outlier threshold estimation is not always appro priate for stations with unregulated, natural basins in Texas. Asquith and others (1995) present an equation3 to estimate low-outlier thresholds for stations in the State. The equation estimates low-outlier thresholds by using the mean, standard deviation, and skew of the logarithms for the systematic annual peak discharges. To estimate a low-outlier threshold using the equation from Asquith and others, two PEAKFQ analyses for the same station are necessary. The first run of PEAKFQ calculates the mean, standard deviation, and skew of the logarithms for the systematic record. These parameters are found in the output file from PEAKFQ. For station 08150700, the logarithmic mean is 4.2452; the logarithmic standard deviation is 0.7782; and the
3The equation of Asquith and others (1995) is not presented here because discussion of its use and limitations is beyond the scope of this report.
logarithmic skew is -0.937. Using the equation, the low-outlier threshold is estimated at 1,748 ft3/s. PEAKFQ is now run again with a "Lo-outlier threshold" of 1,748 ft3/s: Type "1748" for the "Lo-outlier threshold," and type "F2" to perform the peak-streamflow-frequency analysis.
The next screen indicates that the station has been processed and the analysis written to the output file. Pressing "F2" will return to the opening screen. To return to DOS select "Return" and press "F2." The out put file can be viewed using any text editor in DOS or can be printed to a printer.
