ABSTRACT

This report presents water-quantity and water-quality data for samples

collected at wells, springs, streams, and lakes in the vicinity of Mount Shasta

in northern California. The data are presented in graphs and tables. Ground-

water data include water-level measurements made at 24 wells, analyses of water

collected at 12 wells, discharge measurements made at 14 springs, and analyses

of water collected at 17 springs. Surface-water data include streamflow meas­

urements and(or) analyses of suspended sediment collected at 36 stream sites;

analyses of water samples collected at 11 stream sites; profiles of tempera­

ture, specific conductance, dissolved oxygen, and pH for water samples from

6 lake sites; and analyses of water samples collected at 7 lake sites. Maps

of the area show the location of data-collection sites.

ABSTRACT 1

INTRODUCTION

Mount Shasta in northern California is a stratovolcano near the southern end of the chain of Cascade Volcanos. The volcanic history of the mountain implies that Mount Shasta will erupt sometime in the future (Miller, 1980).

Purpose and Scope

As a part of an assessment of the water resources in the Mount Shasta area, water-quantity and water-quality data were obtained from March 1981 to August 1984 at wells, springs, streams, and lakes in an 800-mi 2 area in the vicinity of Mount Shasta (figs. 1 and 2). The assessment will be prepared as a benchmark to compare possible changes due to land use, volcanic activity, or other natural events. This report contains ground- and surface-water data to provide a documentation of the 1981-84 ground-water levels, discharges, temperatures, and chemistry of surface and ground water, in addition to previously published streamflow data.

Location of Sites

Measurement and sampling sites to be included in the data-collection program (figs. 1 and 2) were selected to provide complete areal coverage of the flanks of Mount Shasta. A lack of development on the northeast side of the mountain restricted the location of well sites to the north, west, and southeast sides of the mountain. Known spring sites are rare on the dry northern slopes, which restricted spring-sampling sites to the west, south, and east sides. Most creeks draining the slopes of Mount Shasta are inter­ mittent and carry water that disappears completely into the sandy soils before it reaches easily accessible locations. This influenced the location of stream-sampling sites and the frequency with which the sites could be sampled. Mount Shasta has no large natural lakes on its flanks, but reservoirs provide lake-sampling sites on the northwest, west, and south sides of the mountain. Medicine Lake and Mosquito Lake, approximately 30 miles northeast and east of the Mount Shasta summit, provide lake-sampling sites in the rain shadow of the mountain.

Previous Data-Collection Activities

No previous water-data-collection program in this area has encompassed the area and scope of the present study. Previous studies have, however, included parts of the area covered in this report or other nearby areas. The ground water in the Shasta Valley was reported in Mack (1960), and the develop­ ment of these water resources was discussed by the California Department of Water Resources (1961). Miscellaneous water-quality data were collected on Mud and Squaw Valley Creeks in 1959-61 and on Wagon Creek in 1965 by the California Department of Water Resources (written commun., 1982). Prior to the construction of the Box Canyon Dam on the Sacramento River, the California Department of Water Resources (1964) conducted investigations that included a water-supply study for the city of Mount Shasta and the Dunsmuir area. Data for springs near the city of Mount Shasta and in the Shasta Valley are reported in Berkstresser (1968). Water-bearing properties of some of the geologic units southwest of the city of Mount Shasta were discussed by Bertoldi (1973). A limnological study of Shasta Lake emphasizing the effects of the 1977 drought was reported by Rettig and Bortleson (1983). Surface-water records have been published for sites in the vicinity of Mount Shasta on the Shasta, the Sacramento, and the McCloud Rivers since 1934, 1945, and 1932, respectively (U.S. Geological Survey, 1959, 1964, 1970, 1972-75, 1976, and 1976-82).

METHODS

Historical discharge data contained in this report were summarized from published sources (U.S. Geological Survey, 1959; 1964; 1970; 1972-75; 1976; and 1976-82). For the present study, field data and samples for laboratory analysis were collected at 24 wells, 17 springs, 36 stream sites, and 7 lake sites.

Discharge

Discharge measurements reported for streams and springs were the result of wading measurements using Price AA or Pygmy meters according to U.S. Geological Survey procedures (Buchanan and Somers, 1969). Outside reference marks were established at most sites for comparison of water-surface elevations.

6 WATER-RESOURCES DATA, MOUNT SHASTA AREA

Water Quality

The field parameters measured at all water-quality sites included (1) temperature, by hand thermometer; (2) pH, by field instrument; (3) specific conductance, by field instrument; (4) alkalinity, by 4.5-pH end-point titration with a field instrument; and (5) dissolved oxygen by field Winkler titrations. Field instruments were calibrated immediately before each use.

Samples taken at each site were split and filtered immediately after sampling. They were kept chilled and in the dark until the end of the sampling run. The samples then were packed in chilled containers and sent via Express Mail to the U.S. Geological Survey Central Laboratory in Arvada, Colorado.

All samples were analyzed for major ions and nutrients. Water samples from wells, springs, and streams also were analyzed by semiquantitative methods for trace metals which yielded a rounded value for concentration of trace metals. Values below a specified lower limit or above an upper limit were reported, respectively, as "less than (<)" or "greater than (>)" results. Results were rounded to the nearest step of 1, 3, 5, 7, or 10. For example, a result that had a true value of 0.043 mg/L (milligram per liter) was reported as 0.050 mg/L, and one that had a true value of 0.035 mg/L was reported as 0.030 mg/L. The precision of a reported value is plus or minus one step at one standard deviation (E. J. Zayhowski, U.S. Geological Survey, written commun., 1983).

Stream samples were obtained using a depth-integrating hand sampler (DH-48) and by the equal-discharge increment method. Spring samples were taken using a battery-powered peristaltic pump with a long length of tygon tubing which permitted sampling as close as possible to the spring source. Samples were obtained at wells at the point source nearest the pump.

Lake samples, obtained by using a Van Dorn sampler at various depths, were composited in a churn splitter to form one sample per site. Depth profiles were conducted at 1-meter intervals at each lake site. A Martek Mark VI instrument, calibrated prior to each use, was used to measure parameters of pH, temperature, conductance, and dissolved oxygen. Light penetration was measured using a standard Secchi disc.

Suspended Sediment

Suspended-sediment samples were collected using a DH-48 sampler and by the equal-discharge increment method. These samples were analyzed for concen­ tration of suspended sediment, percent sand, and particle-size distribution at the U.S. Geological Survey Sediment Laboratory in Sacramento, California.

METHODS 7

WELLS

In the study area, ground water from wells is an important source of domestic water supply for the communities of Weed, Mount Shasta (City), and McCloud. It also is an important source of water for domestic and agricultural use in the outlying areas.

The wells in this report are listed by well number. The well-numbering system used by the U.S. Geological Survey in California indicates the location of wells according to the system for the subdivision of public lands. For example, in the number 40N/4W-6F1, the part of the number preceding the slash indicates the township (T. 40 N.), the number after the slash indicates the range (R. 4 W.), the digits after the hyphen indicate the section (sec. 6), and the letter after the section number indicates the 40-acre subdivision of the section as indicated on the diagram below. Within each 40-acre tract, the wells are numbered serially as indicated by the final digit of the well number. Thus, well 40N/4W-6F1 was the first well to be listed in the northeast quarter of the northwest quarter of section 6. The entire study area is north and west of the Mount Diablo base line and meridian.

8 WATER-RESOURCES DATA, MOUNT SHASTA AREA

The U.S. Geological Survey site-numbering system is based on the grid system of latitude and longitude which provides the geographic location of the well and a unique number for each site. The number consists of 15 digits; the first 6 digits denote the degrees, minutes, and seconds of latitude; the next 7 digits denote degrees, minutes, and seconds of longitude; and the last 2 digits (assigned sequentially) identify the wells or other sites within a 1-second grid.

Water Levels

Ground-water levels were continuously recorded in two wells from August1981 to September 1982 (fig. 2). Hydrographs show the fluctuation of water levels in each well (figs. 3 and 4).

Ground-water levels in 22 wells (fig. 2) were measured by steel and electric tape at approximately monthly intervals from July 1981 to October1982 and again during June and August of 1983. Water-level data from these measurements are given in table 1. (Tables are at back of report.)

WELLS 11

SPRINGS

The cities of Weed, Mount Shasta, McCloud, and Dunsmuir depend on springs as their major source of community water supplies. The discharge of other untapped springs supplies surface-water flow to numerous creeks and rivers, including the Sacramento and the McCloud Rivers.

The names of springs included in this report are the names shown on the U.S. Geological Survey topographic maps, most of which have been confirmed to be in common usage. If no name was indicated on the maps, the authors assigned a name that included the name of a nearby landmark. Spring locations shown in figure 2 are described in table 4 and are assigned a spring number. The spring-numbering system is the same as the well-numbering system described on page 7; an S is added before the final digit of the spring number.

Discharge

Discharge data for 14 springs (fig. 2) measured from April to September 1981 and during August 1982 are presented in table 4.

Water Quality

Water samples from 13 springs were collected for chemical analyses from May to September 1981. Two of these springs were resampled during August and September 1982; four additional springs were sampled at this time, bringing the total number of springs sampled to 17 (fig. 2). Results of the onsite analyses and laboratory analyses for major ions and nutrients are presented in table 5. Results of the semiquantitative analyses for trace metals in springs are given in table 6.

Water samples were taken from a thermal spring west of the summit of Mount Shasta at an altitude of 14,000 feet, and onsite measurements were made on August 13, 1981. Onsite measurements included temperature only due to the inaccessability of the site. Results are included in tables 5 and 6.

12 WATER-RESOURCES DATA, MOUNT SHASTA AREA

STREAMS

Glacial melt, snowmelt, and rain supply water to the numerous creeks that drain the slopes of Mount Shasta. Most of the precipitation falls during October through June. Annual precipitation averages 37.49 inches at the Mount Shasta (City) (National Oceanic and Atmospheric Administration, 1981-83) and over 60 inches at higher altitudes (California Department of Water Resources, 1964). Annual precipitation for the 1981, 1982, and 1983 water years was 47.69, 51.64, and 64.93 inches respectively (National Oceanic and Atmospheric Administration, 1981-83). Glacial melt supplies water during the summer. Whitney and Bolam Glaciers feed Whitney and Bolam Creeks, Wintun Glacier feeds Ash Creek, Konwakiton Glacier feeds Mud Creek, and Hotlum Glacier feeds Gravel Creek.

Tributaries to the McCloud River, which drains the southeast flanks of Mount Shasta, include Ash Creek, Mud Creek, Big Springs near McCloud, and Muir Springs below Lower Falls. Tributaries to the Sacramento River that drain the slopes of Mount Shasta include Big Canyon Creek and Big Springs near Mount Shasta (City). The Shasta River is supplied from the west by drainage from the slopes of Mount Shasta. Big Springs near Grenada, tributary to the Shasta River, is recharged on Mount Shasta.

The location of gaging stations on the Shasta, the Sacramento, and the McCloud Rivers is shown in figures 1 and 2; the station descriptions and measurements are shown in table 7. Discharge measurements were made at miscellaneous sites named according to creek name and nearby landmarks. Locations of miscellaneous streams sites shown in figure 2 are described in table 8, according to quarter section of township and range and the distance and direction from major landmarks.

Gaging Stations

Monthly and yearly mean discharges calculated from daily streamflow data obtained at the continuous-record gaging stations are listed in table 7. The gaging stations are located on major streams on the flanks of Mount Shasta and include the Sacramento, the Shasta, and the McCloud Rivers (figs. 1 and 2). Maximum and minimum yearly discharges for the complete period of record for each of the rivers also are given in table 7. The station numbers are the downstream-order numbers used in the U.S. Geological Survey streamflow-gaging system (U.S. Geological Survey, 1972-75; 1976-82).

STREAMS 13

Miscellaneous Sites

There were no continuous-recording streamflow gages operating on the creeks draining the slopes of Mount Shasta during the study period. Hydro- graphs of flow data obtained at temporary continuous-recording gages operated on Mud Creek from August 18 to November 2, 1981, and on Whitney Creek from August 18 to November 2, 1981 (no flow October 14 to November 2), and from August 13 to October 4, 1982 (no flow September 16 to October 4) are shown in figures 6 and 7. Measurements were made at miscellaneous sites on Ash, Bolam, Gravel, Inconstance, Mud, Pilgrim, Squaw Valley, and Whitney Creeks (fig. 2) during May through September 1981 and again during July through August 1984. Measurements were made at miscellaneous sites on Brewer, Cascade Gulch, and Cold Creeks during July through August 1984. Results of these measurements are shown in table 8.

Suspended Sediment

In conjunction with discharge measurements, suspended-sediment samples were collected at 25 sites on 9 creeks during May through August 1981 and at 11 sites on 11 creeks during July through August 1984. Concentrations of suspended sediment and percentage sand are given in table 8. Six samples from four sites were analyzed for particle-size distribution. Results are shown in table 9.

Water Quality

Samples of stream water were collected at 11 sites during May, July, and September 1981 (fig. 2). Results of the onsite analyses and laboratory analyses of major ions and nutrients are presented in table 10. Results of the semiquantitative analyses for trace metals at nine of the sites are given in table 11.

LAKES

Siskiyou, McCloud, and Shastina Lakes are reservoirs used for recreation and regulation of flow of the Sacramento, the McCloud, and the Shasta Rivers, respectively. Siskiyou Lake was filled in 1968 after construction of the Box Canyon earthfill dam. Lake McCloud Dam, a rockfill dam, was constructed in 1965. Lake Shastina Dam was completed in 1928. Medicine Lake and Mosquito Lake are natural lakes.

Water Quality

During the summer of 1981, water samples were collected at seven sites on the five lakes. Two sampling sites one at the dam and the other at the upstream end--were chosen at each reservoir except at the dam on Siskiyou Lake where a sampling site was not selected due to weather conditions and time limitations. The locations of the sampling sites on the reservoirs are shown in figure 2. At the natural lakes, Medicine Lake and Mosquito Lake, samples were obtained at the deepest portion of the lakes. The locations of the sampling sites on the natural lakes are shown in figure 1. Results of the laboratory analyses for major ions and nutrients are given in table 12.

Depth Profiles

Depth profiles were conducted at each lake site, except Mosquito Lake which was approximately 3 feet deep. The data from the profiles are plotted in figures 8 through 13.
