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
