22 Evaluation of the Hydrologic System and Selected Water-Management Alternatives in the Owens Valley, California
C

U.S. Government lands, either Forest Service or Bureau of Land Management, are located generally in the mountains and along the edge of the mountains or on the Volcanic Tableland. Of the 307,000 acres owned by the Los Angeles Department of Water and Power in the Owens Valley and the Mono Basin drainage basins, most of the land (240,000 acres) is located on the valley floor of the Owens Valley.
The main economic activities in the valley are livestock ranching and tourism. About 190,000 acres of the valley floor is leased by the Los Angeles Depart-ment of Water and Power to ranchers for grazing and about 12,400 additional acres is leased for growing alfalfa pasture. Access to most lands in the mountains and the valley is open to the public, and tens of thou-sands of people each year utilize the many recreational benefits such as hunting, fishing, skiing, and camping.
Since the early 1900's, water use in the Owens Valley has changed from meeting local needs, such as ranching and farming, to exporting some surface water, to exporting a greater quantity of both surface and ground water. The major historical periods with similar water use are summarized in table 4.
As of 1988, water use within the valley involves both surface-water diversions and ground-water pump-ing. About 1,200 to 2,000 acre-ft/yr of ground water is supplied to the four major towns in the valley—Bishop, population 10,352; Big Pine, population 1,610; Inde-pendence, population 655; and Lone Pine, population 2,062 (U.S. Department of Commerce, 1990). Other in-valley uses of water are for Indian reservations and for stockwater, irrigation of pastures, and cultivation of alfalfa. Fish Springs and Blackrock fish hatcheries rely on ground water, and the Mt. Whitney fish hatchery

was to measure evapotranspiration at representative vegetation study sites throughout the valley (fig. 2), to relate these data to soil and plant characteristics at the sites, to extend the relations to quantify evapotranspi-ration throughout the valley, and then to synthesize the results in an analysis of the overall hydrologic system.
As part of the studies of native vegetation, Duell (1990) used micrometeorologic equipment to collect detailed evapotranspiration measurements during 1984–85, a period of relatively abundant surface water and ground water in the valley. The results for high-ground-water alkali meadow and alkali scrub com-munities (fig. 6 and table 3), which are summarized in table 5, show that evapotranspiration rates on the valley floor ranged from about 12 in/yr to about 45 in/yr depending on the type and percentage of vegetative cover. Assuming that these rates are representative of average conditions on the valley floor where the depth
to water is approximately 3 to 15 ft, then evapotran-spiration is about 3 to 6 times greater than the quantity of precipitation that is available.
During the same period and at the same sites, Groeneveld and others (1986a, 1986b) collected tran-spiration measurements from native vegetation using a porometer, an instrument that encloses a few leaves of a plant and measures water-vapor flux (Beardsell and others, 1972). These measurements can be converted to transpiration from an entire site using measurements of total leaf area per plant and plant density per site. Results from Groeneveld and others (1986a, p.117) suggest that most of the evapotranspiration measured by Duell (1990) is transpiration from native vegetation.
Coincident monitoring of soil moisture at the same sites indicated that most of the transpired water came from the unsaturated zone, including that part just below the land surface. These findings indicate that the

rates of infiltration. In general, tributary streamflow increases from south to north much as precipitation does (fig. 7).
As expected from precipitation patterns (fig. 7A), discharge from tributary streams on the east side of the valley is much less than discharge on the west. Only two streams produce a reliable source of water each year—Coldwater Canyon and Silver Canyon Creeks (fig. 11), and these streams typically discharge less than 2,000 acre-ft/yr. Farther south, Mazourka Creek was monitored by the U.S. Geological Survey continuously during 1961–72 (Mazourka Creek near Independence, USGS station 10282480). Zero flow was recorded all days except during two brief periods in 1967 and 1969. During these periods, discharge peaked at more than 1,300 and
600 ft3/s, respectively. This type of large, infrequent runoff is characteristic of other basin-and-range valleys (Fenneman, 1931, p. 329) and probably is typical of most stream drainages along the east side of the Owens Valley south of Silver Canyon Creek (fig. 11).
Percent Valleywide Runoff
Total runoff for the Owens Valley is highly correlated with flow in individual tributary streams and has been calculated by the Los Angeles Department of Water and Power (M.L. Blevins, written commun., 1988; table 5) for water years 1935–88. Total runoff is defined as the sum of inflow from the Owens River at the Pleasant Valley Reservoir, measured and estimated inflow from tributary streams, and estimated mountain-

1976
Long-term average annual runoff for the Owens Valley was calculated for water years1935-84 by the Los Angeles Department of Water and Power (station OUKR, table 6;M.L. Blevins, written commun., 1988). Annual runoff for the Owens Valley commonly is expressed as a percent of long-term average annual runoff and is referred to locally aspercent valleywide runoff or percent runoff year. Refer to table 7 for annual values

whereR G is stream recharge to the aquifer system for
the reach between the base-of-mountains and river–aqueduct gages, in acre-feet per year;
S BM is measured stream discharge at the base-of-mountains gage, in acre-feet per year;
S RA is measured stream discharge at the river–aqueduct gage, in acre-feet per year;
W G is measured well discharge that flows into the stream between the base-of-mountains and river–aqueduct gages, in acre-feet per year; and
ET G is the estimated evapotranspiration between the two gages in the immediate vicinity of the stream channel, in acre-feet per year.
Streamflow data for a 50-year period, water years 1935–84, were used to determine the loss for each tributary stream, defined as the sum of R G and ET G. Because all other values in equation 4 are

ANNUAL RUNOFF, IN PERCENT OF AVERAGE ANNUAL RUNOFF
EXPLANATION
Average annual runoff for the Owens Valleywas calculated for water years 1935-84by the Los Angeles Department of Waterand Power (station OUKR, table 6; M.L.Blevins, written commun., 1988). Annualrunoff for the Owens Valley commonly isexpressed as a percent of long-term average annual runoff and is referred tolocally as percent valleywide runoff orpercent runoff year; refer to table 7 forannual values
Antecedent relation – Based on quantityof runoff in preceding water year. Annualpumpage is greater when antecedentconditions are dry

aquifer recharge and discharge resulted in greater fluctuations in ground-water levels.
Underflow
Underflow into and out of the aquifer system occurs at several locations shown in figure 14. Under-flow from three drainages (Bishop and Big Pine Creeks and Waucoba Canyon) originates as recharge from tributary streams outside the aquifer system. For that reason, the quantity of underflow from those areas, totaling about 500 acre-ft/yr, is included for water-budget purposes as part of tributary stream recharge (table 10).
The quantity of underflow from Round Valley, the Volcanic Tableland, and Chalfant Valley is much greater and was estimated to average about 4,000 acre-ft/yr (table 10). Prior estimates of underflow from these areas were significantly higher, totaling as much as 25,000 acre-ft/yr. These estimates were based on Darcy's law (Los Angeles Department of Water and Power 1972, 1976, 1978, 1979) and on steady-state ground-water-model simulations (Danskin, 1988). As shown in table 10, the quantity of underflow into the aquifer system is not known with certainty. However,
the present estimates, which are consistent with results from several different ground-water flow models developed during the cooperative USGS studies, probably are more accurate than previous estimates. The models also are based on Darcy's law, but they have additional advantages; these include incorpora-ting nearby ground-water recharge and discharge, accounting for changes in ground-water storage, and matching various historical conditions (calibration).
Underflow out of the aquifer system occurs only across an arbitrary east–west line south of Lone Pine. In the area east of the Alabama Hills, most ground water flows out of the aquifer system through hydrogeologic unit 3, which is thicker and more transmissive than hydrogeologic unit 1. In the area west of the Alabama Hills, hydrogeologic units 1 and 3 act together, and there is no clear distinction between the two units, or indication of the relative quantity of underflow from each. Total underflow from both areas was estimated to be about 10,000 acre-ft/yr. This estimate is based on calibration of the valleywide ground-water flow model and on a water-budget analysis of the Owens Lake area by Lopes (1988). No difference in the quantity of underflow before and after 1970 was detected (table 10).

Some areas on the valley floor that have a simulated decline in water-table altitude greater than 10 ft are areas that are covered with native vegetation identified as susceptible to stress from pumping (R.H. Rawson, Los Angeles Department of Water and
Power, written commun., 1988; Sorenson and others, 1991). The significant water-table decline in these areas decreases evapotranspiration, prompts native vegetation to drop leaves, and reduces total biomass on the valley floor. Some species, such as rabbitbrush

Shown are changes in percent of average annual runoff, annual pumpage, and water-table response at typical locations in the valley during the 9-year simulation period.
