Abstract
Fluctuations of Water Level, Water Quality and Biota of Great Salt Lake, Utah, 1847–1986
Abstract
Great Salt Lake is the fourth largest terminal lake in the world, covering about 2,400 square miles. The lake is bordered on the west by barren desert and on the east by a major metropolitan area, Since its historic low elevation of 4,191.35 feet in 1963, the lake has risen to a new historic high elevation of 4,211.85 feet in 1986. Most of this increase (12.2 feet) has occurred since 1982, causing $285 million of damage to lakeside industries, transportation, farming, and wildlife. Accompanying the rapid rise in lake level has been a decrease in salinity from 28 percent in 1963 to about 5 percent in 1986, This has resulted in changes in the biota from obligate halophiles to opportunistic forms such as blue-green algae, and most recently, a brackish- water fish.
