r1MPQSE_ AND SCOPE -

A. General - This report presents stage-frequency curves for 24 tide gage locations,

wave runup data for 12 locations and 50-, 100- and 300-year maximum water-surface

elevation plots around the islands in the Sacramento-San Joaquin Delta. The stage-

frequency curves in this report are updates to the stage-frequency curves presented in

the report entitled "Sacramento-San Joaquin Delta, California, Stage-Frequency Study,

Hydrology" and dated December 1976. The stage-frequency curves in this report

include stage data recorded through water year 1988.

B. Exclusions - This report does not address FEMA guidelines. The stage-frequency

curves do not reflect any expected probability adjustment. The stage-frequency

curves and maximum water-surface elevation plots reflect present conditions. They do

not show the effects of any proposed dams, levee improvements, possible levee

failures or Delta operational changes.

C. Interior Drainage - A study of interior drainage for the Delta islands was not

included in the scope of this report. At this time it is not known if projects win be

feasible on any of the islands. Any future levee improvement projects will address

interior drainage on a-case-by-ease basis.

D. Delta Maximum Water-Surface Elevation Plots - The maximum water-surface

elevation plots presented in this report were not developed using a hydraulic model.

They were derived from the stage-frequency curves by, in most cases, straightlining

between gaging stations. See page 13 for an explanation.

E. Future Conditions - The effects on the stage-frequency curves and maximumwater-surface elevations due to future land development were not studied. Due to the

size of the drainage area contributing flow to the Delta, it is not expected that land

use changes will have an appreciable effect on the water-surface elevations in the

Delta.

If future projects include levee raising or construction of new levees, then these

features will have to be analyzed to determine their impacts on the water-surface

elevations at adjacent locations. Possible impacts would have to be studied when a

particular project is proposed.

F. Usage - The data provided in this report will be used in Phase I of the

Sacramento-San Joaquin Delta Special Study. The purpose of the Special Study is to

recommend islands or groups of islands for possible levee projects. The Special Studywill use the maximum water-surface elevation plots to perform the following:

A. The 300-year water-surface will be used to estimate levee construction

costs.

B. Determine the approximate probability of overtopping at levee low spots.

C. To set stages within the islands to compute damages.

I

The levee construction cost information will be used as part of the benefit-cost

economic analysis which will determine the feasibility of a proposed levee project.

The islands selected in Phase, I will be analyzed in Phase 11. Phase 11 will be a

feasibility level study. During the Phase 11 study, it will be necessary to determine

what effects a proposed levee project will have in the surrounding area and if any

mitigation measures are necessary. The method of analyzing these effects win be

determined when Phase I is completed and it is known which islands will be

recommended for Phase 11 studies. It is possible that hydraulic modeling will be

necessary.

Phase 11 studies should include some type of risk analysis to determine the final NEDplan.

G. 1,evee Crown Profiles - Levee crown profiles plotted on Charts 27-74 were

surveyed by the Engineering firm retained by,44fe respective Reclamation District.

Dates of the surveys are shown on Table

2. RESULTS - Locations of Delta gaging stations ~an be found on Chart 1. Stage-frequency

curves are plotted on Charts 2-25. Locations where wave runup calculations were made are

shown on Chart 26. Charts 27 through 74 show the 50-, 100- and 300-year maximum water-

surface elevations around the Delta Islands. Charts 76 through 91 show the levee stationing

around each island. Caution should be used when using the stationing on the water-surface

plots since station zero on the plot is not always at the same location as station zero on the

base map. Column 4 of Table 8, pages 16 and 17, lists the station on the base map that

corresponds to station zero on the water-surface plots for each island. Tables 3 through 5,

pages 9-11, list yearly maximum stage readings at each gage location in the Delta. Table 6,

page 12, tabulates the 50- and 100-year stages. Table 7, page 15, tabulates the wind-wave

calculations. The adequacy of the results of the study along with general assumptions are

presented on page 7, paragraph C.

3. STUDY AREA -

A. General - The Delta, which covers more than 1,000 square miles, is in Central

California. It is situated upstream of the confluence of the Sacramento and San

Joaquin Rivers at the head of Suisun Bay, the most easterly extending arm of the San

Francisco Bay system. In general, the Delta extends from about Sacramento on the

north, to Stockton on the south, and near Pittsburg on the west, This region, which

is very flat, has been reclaimed from a natural tidal area by hundreds of miles of

levees along natural and manmade waterways that divide it into about 100 tracts

locally know as "islands". Land elevations range from just above mean sea level to

10 feet below mean sea level. Before islands were reclaimed, much of the Delta wascoveted by water from the daily tide cycle. During times of high runoff from the

Sacramento and San Joaquin Basins, much of the Delta would be flooded. Chart I is

a map of the Delta region.

B. ]Flood Characteristics - The contributing drainage area to the Sacramento-San

Joaquin Delta encompasses approximately 40,000 square miles. Chart IA shows the

2

contributing drainage area and Table I lists the approximate drainage areas.

Chart 1A and Table I show that the Sacramento-San Joaquin Delta derives its name

from it's two main contributors, the Sacramento and San Joaquin Rivers. Flows in

these systems come from areas that are geographically and physically different.

A review of annual maximum stages in the Delta shows that in some years the annual

maximum stage at all locations will be occur during the same storm event. However,

in other years, the peak stages in the northern part of the Delta occur during a

different time period than those in the southern part of the Delta and vice versa. Ile

differences are caused by the geographical distribution of the contributing drainage

basin and the fluctuation of the storm track over California. If the main section of a

storm system drops it's precipitation over the Sacramento River basin, the stages will

be higher in the northern part of the Delta. If the main section is over the San

Joaquin, then the stages will be higher in the southern part.

Also contributing to the puzzle is the tidal influence of the Pacific Ocean. The tides

can have a profound effect on the stages especially in the lower and central parts of

the Delta. If high tides combine with high runoff events very high stages will result.

In summary, the maximum stages result from storms of different origins which do not

have the same frequency at all locations, and from tides of varying magnitudes which

seldom reach their maximum stages concurrently with the peak flows.

C. Tidal Hydraulics - The normal tide cycle has two high stages and two low stages

in a day. Tides follow the moon more closely than they do the sun, and the lunar or

tidal day is about 50 minutes longer than the solar day. This causes the tide to occur

later each day, and the tide that has occurred near the end of one calendar day will be

followed by a corresponding tide that may skip the next day and occur in the early

morning of the third day. Thus on certain days of each month only a single high or

single low water occurs. At some stations, during portions of each month, the tide

becomes diurnal, that is, only one high and one low water will occur during the

period of a lunar day.

During a low flow period, tidal effects can be seen on the Sacramento River at

Verona and the San Joaquin River at Mossdale. During periods of high flow, the

3

tidal effects are dampened upstream of the delta. As the high flows enter the Delta,

they are affected by the tidal cycle. The hourly gage readings in the central and

lower sections of the Delta will reflect the tidal variation, even during high flow

periods.

The times that high flows are concurrent with high tides in the delta is when extreme

elevations occur. The incoming tide from the Pacific Ocean will have a tendency to

slow down and backup the incoming high flows to the Delta. When this "stacking"

occurs, especially with high wind periods, levee flood fights are a common sight.

4. $TAGE-FREQIJENCY ANALYSIS -

A. General - Selection of gages for analysis in this study was based primarily on

availability of records. The 24 gages selected were judged to have the most suitable

records and proper areal distribution in the Delta. The datum of most of the gages

selected has changed one or two times during the period of record. Therefore, all of

the records were adjusted to a datum of zero elevation, mean sea level (NGVD of

1929) to maintain continuity among all stations. Table 2 shows the gages analyzed.

B. Stage Data - Many stage recording gages have been installed in the Delta over the

past 50-60 years. Depending on the need for information at specific sites, some gages

have been short lived while others have a long record. Until 1976, stage data were

published annually in the 130 Series Bulletins of the California Department of Water

Resources. Since 1976, stage data are being stored by the California Department of

Water Resources Central District Office, Data and Operations Branch, Sacramento,

California. This agency is to be contacted for obtaining unpublished tidal records.

The many factors influencing stages in the Delta include tides, inflow from Central

Valley streams, and high winds. Barometric pressure, land subsidence, recorder

malfunction, vandalism, and other miscellaneous factors also may influence readings

from continuously recording stage gages. Stage data known to be erroneous due to

gage malfunction or some other cause are adjusted prior to their publication.

Land subsidence, which is constantly occurring in the Delta, results in erroneously

high readings. Bench marks throughout the Delta are periodically resurveyed to

correct for land subsidence. When a bench mark is updated, the tide gage datum is

resurveyed and updated by the agency maintaining the gage. Department of Water

Resources and Corps of Engineers tide gages were updated in 1976. Currently, the

Delta area is in the process of being included in the Global Positioning System (GPS).

This system, using data from satellites, will tie the benchmarks in the Delta to those

in the more geologically stable foothill areas in order to access subsidence in the

Delta and adjust the benchmarks to correct for subsidence.

Tables 3 through 5 summarize the higher-high stage data, adjusted to mean sea level,

that have been recorded at the stations listed in Table 2. The period of 1945-1988

was selected for analysis. 'Ibis period covers the maximum length of record for most

stations, coincides with the post Shasta era and the hydraulics of the Delta have not

significantly changed during this period. Operation of the major storage projects in

the Sacramento River Basin is coordinated with operation of Shasta Dam to maintain,

as much as possible, decreed water quality standards near Antioch.

Stage data for each station were compared with data from neighboring stations and,

when necessary, adjusted to obtain consistency. Ilese data were plotted using

weibull plotting positions. The weibull equation is shown below.

P= ---~L

N+1

Where:

P=Plotting Position

M=Order of sequence with 1

being largest

N=Number of items in data set

Curves were then drawn graphically to fit the data. The curves are shown on Charts

2 through 25. Once the curves were drawn they were reviewed as a group and

adjusted, if necessary, to maintain consistency. This review showed:

1. The statistical parameters were inconsistent from gage to gage along the sameriver.

2. The computed frequency curves do not reflect inundation of large areas from levee

6

failures. The curves were smoothed to remove any localized effects of a levee

failure.

3. The maximum elevation on a stage-frequency curve does not exceed the height of

the levee crowns at that location. The curves are drawn solid up to the 100-year

level. This reflects the reliability of the gaged data. Above the 100-year elevation, the

stage-frequency curves are dashed. The curves are dashed above the 100-year level

due to the many uncertainties that can occur at the higher frequencies. No stations

have a period of record long enough to have actual data that would have a plotting

position rarer than the 100-year event. Therefore, in order to estimate elevations of

frequencies greater than the 100-year, the curves are extrapolated based on judgement

and the shape of the curve below the 100-year. The height of the adjacent levee

crown is also taken into account. The stage-frequency curves do not exceed the

height of the adjacent levee crown.

C. Results - The 50- and 100-year higher-high stages at the 24 stations used in the

analysis are shown in Table 6. In an attempt to determine the conditions that would

cause a 100-year ffood stage, or any other high flood stage, historical events were

examined to establish the influence of wind, flood inflow, tidal cycle and barometric

pressure on Delta stages. It was concluded that many combinations of thew

parameters could be possible, each with a varying degree of probability, and that

predicting the factors which cause a particular high stage, or the effect of changes in

one or more parameters, would be quite difficult.

When the stage-frequency data in this memorandum are used, it must be understood

that:

I-

For any particular frequency, the stage shown on the stage-frequency curve

is valid only for that station. A stage created by any combination of high

flows, tide, extreme barometric pressure, and winds could give a 100-year

stage at one station and something of greater or lesser frequency at

neighboring stations.

2. A maximum water-surface elevation plot developed for a particular

frequency by straight-line connection of elevations from a series of stage-

frequency curves will give an elevation higher, at some locations along the

reach, than a historical event of corresponding frequency, This is due to the

variation in width, depth and bottom slope of Delta-channels. However, the

error resulting from straight line elevations is less than 0.3 foot.

3. The stage data presented are for static water conditions. Wave action from

wind, boats or other sources must be added to any stage data being analyzed.

Wind set and any other hydrologic action that increases stages are reflected in

the static stage data.

1. Sacramento River at Rio Vista - The stage recording gage for the Sacramento

7

River at Rio Vista was relocated from the Army Yard to the Rio Vista Bridge in

1981. The stage-frequency curve for the Bridge location is shown on Chart 4.

Based on the stage-frequency analyses for the American River Study, it was

determined that the 1986 peak stages fell within the 50-90 year frequency, depending

on location. The curve for Rio Vista was drawn to remain consistent with this finding

and with the shape of the stage-frequency curve for Sacramento River at Threemile

Slough. The 1986 peak stage at Rio Vista reflects approximately an 80 year

frequency.

The records at the new and old gage sites have 5 years of overlapping record. The

new location is slightly more than a mile upstream of the old location. However, for

all five overlapping years, the peak stage at the new location was lower than the peak

stage at the old location. There are many questions about subsidence and the

reliability of surveyed bench marks in the Rio Vista area, This area is currently

being included in the Global Positioning System in order to get a better handle on the

amounts of subsidence occuring in the area. No data points are plotted on Chart 4

due to datum uncertainties. The data cannot be adjusted to mean sea level datum until

the benchmark elevations in this area are verified.

5. WM-3YAVEA. General - Wind-wave calculations were made for 12 locations in the Delta. These

locations are shown on Chart 26. Table 7 shows the results of the wind-wave

analysis.

B. Wind Analysis - Wind data from the Stockton Metropolitan Airport was used to

compute the design windspeed. Although Stockton is some distance from some of the

12 locations, it was the closest location for reliable wind data. This analysis found

that high winds can occur from most any direction particularly the North, Northwest

and Southeast,

6. MAXP4UM WATER-SURFACE FLEVATTONS - Maximum water-surface elevations

were developed for the rivers and sloughs in the Delta. The elevations are plotted for the

estimated 1986 water surface, the 50-, 100- and 300-year events. The elevation plots are

shown on Charts 27 through 74.

The 50-, 100-, and 300-year elevation plots represent an estimation of how the 50-, 100-,

and 300-year stages, at the gaged locatigns, translate around the island. These plots should

not be considered as "Profiles" since flmf are derived directly from frequency curves of

recorded maximum annual stages at gaged locations. As was discussed in the section "Flood

Characteristics", on page 3, the annual maximum stages may result from an event that is not

concurrent throughout the Delta. Therefore, the maximum water-surface elevations should

not be considered to be concurrent throughout the Delta. While one area of the Delta is

experiencing maximum elevations, the elevations in other areas will be rising or falling.

Some elevation plots may appear to be "increasing" in the downstream direction.

McCormack-Williarnson Tract, Chart 48, is a good example of this. However, it is

important to remember that all elevations on these Charts are plotted relative to the island.

Charts 75-91, which show island stationing, combined with Table 8, will help determine in

which relative direction the plot was drawn around the island.

The 1986 flood elevations were estimated using recorded gage heights at the respective gage

locations. The 1986 flood elevations reflect levee failures that occured in 1986. The

elevations for the 50-, 100-, and 300-year events were derived using their respective

elevations on the stage-frequency curves. As described in the stage-frequency analysis on

page 4, the stage-fkequency curves reflect a no levee failure situation. Therefore, the,

elevations are so eTe-ia6 n- s.

In almost all cases, the elevation plots were drawn by stmightlining between gaging stations.

However, in areas where no recorded data were available, results from the State of

California's Department of Water Resources Link Node computer model were used to

estimate the water-surface elevation trend. The results of the Link Node model are not

shown in this report. Water-surface profiles shown in the Documentation Report entitled

"Sacramento-San Joaquin Delta, California" and dated October 1982 were also used to helpin determining the water-surface elevation trends between gaging stations on the major rivers

13

in the Delta. Maximum water-surface elevatons on the Mokelumne River, North and South

Forks of the Mokelumne River and Snodgrass Slough were based on results presented in

Appendix C of the "Draft Environmental Report, Environmental Impact Statement, North

Delta Program" prepared by -the California Department of Water Resources and dated

November 1990. In fringe backwater tributary channels of the Delta, it was assumed that the

elevation in the tributary would be the same as in the major channel where the tributary

connects.

7. LEVEE CRQWN PROM~ES - Levee Crown profiles were plotted from surveys

acquired from each reclamation district. Some profiles show localized high points. These,

points are not indicative of the actual freeboard around the island. The levee stationing base

maps, Charts 76-91, show the stationing along each levee crown for each island. Station

zero on a water-surface profile is not always at the same location as station zero on the base

map, Column 4 of Table 8, pages 16 and 17, lists the station on the base map that

corresponds to station zero on the profile for each island.

The levee crown elevation for McCormack-Williamson Tract is mandated by the State of

California Reclamation Board. This island will be allowed to fail during large flood events as

was the case in 1986.
