The concentration of dissolved solids in water from the principal aquifer ranges from about 100 mg/l (milligrams per liter) to as much as 800 mg/l. Water containing the least dissolved solids occurs in an arcuate, mile-wide band along the southern border of the Sugar House quadrangle. Water containing the most dissolved solids occurs in a 3½-mile–wide band in the northern part of the valley, as sh

The depth to the top of the principal aquifer in the Sugar House quadrangle ranges from about 50 feet to more than 400 feet below land surface. The principal aquifer supplied about 4 percent, or 9,000 acre-feet, of the municipal and industrial water used annually in Salt Lake County curing 1964-68. The least depths occur in topographically low areas of the Jordan Valley, such as near Murray in the

Saturated Quaternary deposits in the Sugar Horse quadrangle supply significant quantities of water to wells from which water is withdrawn for domestic, municipal, industrial, and irrigation uses. The deposits consist of clay, silt, sand, and gravel; individual beds range from a few inches to several tens of feet thick. The principal aquifer, which is almost completely within the Quaternary deposit

The depth to ground water in shallow aquifers in the Sugar Horse quadrangle ranges from zero in areas of springs and seeps to more than 10 feet beneath most of the area shown on the map. The depth to water differs from place to place because of irregular topography, and the varying capability of different rock materials to transmit water. Ground water also occurs under unconfined and confined cond

The potentiometric surface is an imaginary surface representing the static head of ground water and defined by the levels to which ground water would rise in tightly cased wells. The potentiometric surface of the principal aquifer within the area of the Sugar House quadrangle ranges from about 20 feet above, to as much as 500 feet below land surface as is shown on the map. The principal aquifer su

The general chemical quality of water was determined from quality-of-water data collected by the U.S. Geological Survey and cooperating State, local, and Federal agencies. Sources of data include springs, and wells that tap aquifers at depths of less than 1,000 feet. In areas where quality-of-water data are inadequate or lacking, the limits of dissolved solids are inferred from geologic data. More

The general availability of ground water was determined from well records collected by the U.S. Geological Survey and cooperating State, local, and Federal agencies. Data are for aquifers that in most places are less than 1,000 feet below the land surface. In areas of few or no wells, potential well yields are inferred from geologic data. Special investigations are needed to determine specific fac

In the Salina quadrangle, as in most of the arid West, summer precipitation commonly occurs as thunderstorms. Suring these storms, rain falls as a torrential downpour, or cloudburst, in a local area. An inch of rain or more may fall in half an hour; U.S. Weather Bureau records show that o.4 inch of rain has fallen in a period of 5 minutes (Woolley, 1946). Such a fall of water far exceeds the absor

This map shows streamflow measured in acre-feet (1 acre-foot Is the amount of water that would cover an area of one acre to a depth of one foot – 43,560 cubic feet or about 326,700 gallons). Streamflow is measured and recorded by the U.S. Geological Survey at gaging stations located at the centers of the blue circles shown on the map. Average annual streamflow is shown by the size of the circles a

A spring is “a place where, without the agency of man, water flows from a rock or soil upon the land or into a body of surface water” (Meinzer, 1923, p. 48).About 450 springs are located on this map. Locations and names are from the U.S. Forest Service maps (1963, 1964) and from topographic maps of the U.S. Geological Survey, both published and in preparation. There is considerable variation in ge
