The tiny brine shrimp (Artemia salina) is one of the few
animals that lives within Great Salt Lake. The brine-shrimp population
plays an important part in the lake's ecosystem, especially in keeping
the lake waters clean through algae consumption. They are also a
major food source for millions of migrating birds.
Other forms of life associated with the lake include brine flies,
algae, and bacteria. Brine flies congregate by the millions along
the lake's beaches, where they feed on bacteria and algae that grow
on rocks or wood. The wind commonly blows the remains of dead brine
flies into long, black, odoriferous windrows or piles along the
beaches. Numerous species of algae and bacteria, which cause the
varied colors of the lake waters, provide food for the brine shrimp.
Ducks, geese, gulls, pelicans, and hundreds of other types of
birds live in the marshes and wetlands surrounding the lake. Great
Salt Lake is an important part of the Pacific and Central Flyways
for migratory waterfowl and part of the Northern Hemispheric Shorebird
Reserve Network.
The shores and nearby wetlands of the lake are also home to a
variety of reptiles and mammals. Eight amphibian, two turtle, nine
lizard, and eight snake species, as well as total of 64 species
or subspecies of mammals have been identified in the Great Salt
Lake area.
How
does the lake affect the weather?
Due to its large size, Great Salt Lake has a significant affect
on the weather of nearby cities. During the winter, the lake is
warmer than the air above it. This increases the moisture content
of the air, creates thermal instability, and causes natural seeding
of salt crystals. These factors are believed to cause the fall and
winter "lake effect," in which areas adjacent to and usually downwind
from the lake receive greater snowfall than those more distant.
What
makes the lake stink?
The unpleasant odor (resembling rotten eggs) that comes from the lake
is a common complaint from those who live near the lake. The odor
results from the decay of plant and animal remains in the shallow
waters around its shores, especially in Farmington Bay. This odor
is especially noticeable when northwest winds blow across the lake,
stir up the shallow waters, and carry the odor landward to populated
regions.
