DATA ON WELLS, SPRINGS, AND THERMAL SPRINGS IN LONG VALLEY, MONO COUNTY, CALIFORNIA

By R. E. Lewis

INTRODUCTION

Purpose and Scope

The U.S. Geological Survey started hydrologic, geologic, and geophysical investigations in Long Valley, Calif., in 1972 as part of a national program of geothermal research. As a result of this research, considerable basic data have been collected. The purpose of this report is to make these hydrologic data readily available. The scope of this report includes the tabulation of recent and historical data from wells, test wells, springs, and thermal springs. Included in these data are water-level measurements or flow rates and water temperatures shown in table 1 and chemical analyses shown in table 2. Temperature gradients (change in temperature with well depth) and bottom hole temperature measurements made in selected wells and test wells are shown in table 3.

Location and General Features of the Area

Long Valley is in southwestern Mono County, in east-central California about 35 mi (56 km) northwest of Bishop (fig. 1). The area included in this investigation encompasses about 270 mi2 (700 km2 ) and includes Long Valley and all its contributory drainage areas. The maximum relief of the area is 5,488 ft (1,673 m). The land-surface altitudes range from about 6,780 ft (2,067 m) above sea level at the surface of Lake Crowley to 12,268 ft (3,739 m) at Mount Morrison in the Sierra Nevada near the southern border of the area. The difference in altitudes within this relatively small area is 5,488 ft (1,673 m) and results in extremes of climate.

Page 4: 7 y - USGSCalifornia about 35 mi (56 km) northwest of Bishop (fig. 1). The area included in this investigation encompasses about 270 mi2 (700 km2) and includes Long Valley and all

Precipitation at Long Valley Dam, altitude 6,800 ft (2,073 m), is about 10 in (25 cm) annually. Precipitation along the Sierra Nevada is considerably greater about 28.7 in (72.9 cm) annually at Mammoth Lakes, Calif., altitude 8,930 ft (2,722 m) and 56.5 in (144 cm) at Mammoth Mountain Pass, altitude 9,500 ft (2,896 m). Between 60 and 70 percent of the precipitation falls as snow during the winter months. Summer temperatures in the valley seldom exceed 90°F (32°C [Celsius]); winter temperatures are commonly below 0°F (-18°C).

The study area covers parts of six topographic quadrangles (fig. 2) The locations of wells and springs are shown in figures 3-13.

Previous Work and Acknowledgments

Most of the hydrologic data from Long Valley are from the prominent thermal springs in the area. The most spectacular area, Casa Diablo, was first mentioned in the literature by Whiting (1888) and Russell (1889), Several of the more prominent thermal springs in the Long Valley area were visited by Waring (1915) and briefly described in his paper on the springs of California. A later paper by Stearns, Stearns, and Waring (1937) repeated Waring f s data with minor additional information; the data from that paper were included in a recent report by Waring (1965) but were not updated. A report by the California Department of Water Resources (1967) proposed a water budget for the valley but was primarily concerned with water quality; numerous chemical and spectrographic analyses of surface water, ground water, and water from springs are included in the report. Kaysing (1970) summarized the general features of the major thermal springs in the area but did not include any chemical analyses of the spring waters in his compilation.

The writer acknowledges the assistance of Messrs. Richard Nakahara and Lindsay A. Swain of the U.S. Geological Survey, Hawaii District, in the field collection of well and spring data and test-well drilling in May-July 1972. The cooperation of the U.S. Forest Service, Bureau of Land Management, and the Los Angeles Department of Water and Power in granting drilling permission on lands owned or controlled by them is greatly appreciated.

Conversion Factors

In this report all water temperatures are reported in degrees Celsius (°C). Temperatures originally reported in degrees Fahrenheit (°F) were changed to °C. Degrees F are converted to °C by subtracting 32° and multiplying by 5/9.

In most reports published since 1900, concentrations of the various chemical constituents are reported in parts per thousand, per hundred thousand, or per million. In this report all concentrations are reported in milligrams per liter. Water containing less than about 7,000 ppm (parts per million) of dissolved solids has a density close to unity, and concentration values, for practical purposes, are the same whether expressed in parts per million or milligrams per liter. However, water containing more than about 7,000 ppm of dissolved solids has a density appreciably above unity, and the concentration values expressed in one unit cannot be equated to those expressed in the other (Waring, 1965, P. 4).

Factors for converting English units to the International System of Units (SI) are given below to four significant figures. However, in the text the metric equivalents are shown only to the number of significant figures consistent with the values for the English units.

Well- and Spring-Numbering System

Wells and springs are assigned numbers according to their location in the rectangular system for the subdivision of public land. For example, as shown in the accompanying diagram, in the well number 3S/29E-2A1 the part of the number preceding the slash indicates the township (T. 3 S.), the part between the slash and the hyphen indicates the range (R. 29 E.), the number between the hyphen and the letter indicates the section (sec. 2), and the letter indicates the 40-acre subdivision of the section.

Within the 40-acre (16-ha) tract wells and springs are numbered serially, as indicated by the final digit. Thus, well 3S/29E-^A1 is the first well to be listed in the NE%NE%, sec. 2, T. 3 S., R. 29 E., Mount Diablo base line and meridian. Springs are numbered similarly except that an S is placed between the 40-acre (16-ha) subdivision letter and the final digit, as shown in the following spring number: 3S/28E-35ES1.

The letter Z, substituted for the letter designating the 40-acre (16-ha) tract, indicates the well or spring was plotted from unverified descriptions; the described locations of such wells or springs were visited, but the data could not be correlated with existing wells or springs.

SHALLOW TEST-DRILLING PROGRAM

Forty-seven test wells were drilled in May, June, and October 1972 and May 1973 using the hollow-stem auger rig. The locations of the wells are shown in figures 3-13. Depth of the holes ranged from 6 to 107 ft (1.8 to 33 m), and the aggregate depth of the holes is 2,478 ft (755 m). The test wells were drilled to obtain (1) the depth to the ground-water surface, (2) geothermal-gradient measurements, and (3) geologic information about the water-bearing properties of the shallow sedimentary deposits.

Polyvinyl-chloride (PVC) pipe, 2 in (5 cm) in diameter, was set in 40 of the holes. Well points, 18 in (46 cm) in length, were placed at the bottom of the PVC pipe in 28 of the holes; slotted PVC pipe was used in 6 holes. In six test wells where drilling was terminated above the water table, closed-end PVC pipe was emplaced and filled with water in order to obtain subsequent measurements of the geothermal gradient.

CLASSIFICATION OF SPRINGS

Strictly defined, any spring (or well) water whose average temperature is noticeably above the mean annual temperature of the air at the same locality may be classed as thermal (Waring, 1965, p. 4). Among European springs that are developed commercially, only those whose temperature is higher than about 20°C are classified as thermal. In the United States, only those springs are called thermal whose temperature is 15 Fahrenheit degrees (8.4 Celsius degrees) above the mean annual temperature of the air at their localities. In areas where the mean annual air temperature is low, some springs that do not freeze in winter because of their natural protective conditions are considered to be thermal; in tropical areas some springs that are only a few degrees warmer than the temperature of the air may be considered thermal.

In the Long Valley area the average annual temperature is about 45°F (7.2°C). By United States standards, then, and for the purpose of this report, any spring having a temperature of 45° + 15°F or 60°F (15.6°C) may be classified as thermal.

TEMPERATURE MEASUREMENTS IN WELLS AND TEST WELLS

Temperature measurements were obtained from selected wells and test wells at various depth intervals using a measuring system borrowed from J. H. Sass of the U.S. Geological Survey in Menlo Park, Calif. The measuring system consisted of a multiconductor cable and hoist, a thermistor thermometer, and a resistance measuring system and is described in detail in Sass and others (1971). Temperatures converted from measured resistances and their depths are shown in table 3.

TABLE 1. Description of wells and springs

LBoxhead explanations are abstracted from U.S. Geological Survey "Instructions for Using the Punch-Card System for the Storage and Retrieval ofGround-Water Data"]

State well number: The wells are identified according to their location in the rectangular system for the subdivision of public land. The identification consists of the township number, north or south; the range number, east or west; and the section number. The section is further subdivided into sixteen HO-acre tracts lettered consecutively (excepting I and 0), beginning with A in the northeast corner of the section and progressing in a sinusoidal manner to R in the southeast corner. Wells within the HO-acre tract are numbered sequentially. The base line and meridian are indicated by the final letter, as follows: H, Humboldt; M, Mount Diablo; S, San Bernardino.Spring number; Springs are numbered similarly. However the letter S is added after the UO-acre tract letter to differentiate the spring from a well.

Owner or user; The apparent owner or user on the date indicated. In some cases, the local name of the well or spring is given.
