PASSAGE THREE (Questions 5-6)
The largest lake in the western United States is the Great Salt Lake, an inland saltwater lake
in northwestern Utah, just outside the state capital of Salt Lake City. Rivers and streams feed into
the Great Salt Lake, but none drain out of it; this has a major influence on both the salt content
and the size of the lake.
Although the Great Salt Lake is fed by freshwater streams, it is actually saltier than the
oceans of the world. The salt comes from the more than two million tons of minerals that flow
into the lake each year from the rivers and creeks that feed it. Sodium and chloride—the
components of salt—comprise the large majority of the lake's mineral content.
depending on long-term weather conditions. During periods of heavy rains, the size of the lake
can swell tremendously from the huge amounts of water flowing into the lake from its feeder
rivers and streams; in 1980 the lake even reached a size of 2,400 square miles. During periods of
dry weather, the size of the lake decreases, sometimes drastically, due to evaporation.
