salt water in the Western Hemisphere. The lake is fed by three rivers (Bear, Weber and Jordon) and has no
outlet. The water level varies with the amount of rainfall and evaporation in the basin. The distinct line
across the center of the lake is the Lucin Cutoff. It is a 30 mile (48 km), east-west causeway built in 1959 to
support a rail line. The causeway connects the cities of Ogden and Lucin and affects the water level of the
lake. Because the lake's main tributaries enter from the south, the water level of the southern section is
several inches higher than that of the northern part. The Great Salt Lake's record high levels in the mid-
1980s threatened the Lucin Cutoff, highways and sewage-treatment plants along the shore-in 1987 pumps
were installed that began draining some of the excess water into the Great Salt Lake Desert to the west. The
resulting new body of water was called the Newfoundland Evaporation Basin-it contains dissolved
minerals, primarily sodium and chloride along with sulfate, magnesium, and potassium. The dissolved
minerals, turbidity and microorganisms which can survive in saline water give the lake its varying colors.
In this photo the north portion is dark red. The crew said that it looked like dirt when they first saw it.
Crews cannot remember the north portion ever looking so red-it is usually a light blue color.
