Map showing depth to top of the principal aquifer, Sugar House quadrangle, Salt Lake County, Utah, February 1972

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 southwest corner of the Sugar House quadrangle. The greatest depths occur near the mountain front in the vicinity of Mill creek and Neffs Canyons where thick alluvial-fan deposits overlie the principal aquifer.
