Construction of the West Desert Pumping Project
was an unprecedented flood control action on the
Great Salt Lake, the largest body of water in
the Western Hemisphere without an outlet to a sea. The project,
designed to enhance the lake's natural evaporation process,
was constructed in record time. Construction began on July
7, 1986. The first of the project's three pumps began operating
on April 10, 1987. The project was fully operational on June
3, 1987.
Between fall 1982 and June 1987, the level
of the Great Salt Lake rose over 12 feet, the tail-end of
a steady rise of nearly 20 feet between 1963 and 1987. The
lake had more than doubled its surface area and increased
its volume three-fold. The lake level reached a modern-day
record 4211.85 feet above mean sea level in 1986 and 1987,
surpassing the historic high of 4211.60 set in June 1873.
At the new record level, the lake covered almost 2,400 square
miles and contained over 30 million acre-feet of water. For
perspective, its expanse was only about 487 square mile less
than the states of Delaware and Rhode Island combined, and
the lake contained an acre-foot of water for every resident
of Utah, Idaho, Wyoming, Montana, Colorado, North Dakota,
South Dakota, Nebraska, Iowa, Kansas, Oklahoma, New Mexico,
Arizona, Nevada, Oregon and Washington. The Great Salt
Lake went on a costly, destructive rampage with its hoarded
inflow from record amounts of snow and rain in Northern Utah.
Shoreline flooding caused an estimated $240 million in damages
to Interstate 80, mineral industries, railway systems, sewage
treatment plants, wildlife habitat, recreation areas, and
public and private property.
Weather experts could predict no immediate
change in the weather, which led to fears that Interstate
80 would be lost to flooding, requiring a new, rerouted freeway.
The Southern Pacific and Union Pacific railroads considered
shutting down operations because of flood damage. Fears grew
that the Salt Lake International Airport would stop flights
because runway drains were starting to fill up. The Great
Salt Lake appeared out of control
Construction and operation of the West
Desert Pumping Project was controversial, and it spawned considerable
public and political debate about costs and alternatives to
pumping lake brine. Concern about the damage caused by the
Great Salt Lake was widespread, but many people harbored hope
the lake would heal itself. The project, however, eventually
won approval from the Utah
State Legislature by a substantial margin as the most
cost-effective and technically sound solution with the greatest
public benefit. Project engineers faced and overcame unique
challenges, including the harsh environment of the Great Salt
Lake, remoteness of the Pumping Plant, and difficult access
to construction areas. The project was nominated for the prestigious
Outstanding Civil Engineering Achievement Award from the American
Society of Civil Engineers and won the society's Civil Engineering
Achievement of Merit Award.
A total of $71.7 million was authorized
for flood control efforts during a special session of the
1986 Utah State Legislature, including $60 million to the
Utah Division of Water Resources, Utah Department of Natural
Resources, to implement the project to pump water from the
Great Salt Lake into the desert area west of the lake.
The pumping project was shut down on June30,
1989, after more than two years of successful operation. The
project pumped about 2.73 million acre-feet of brines from
the lake. The shutdown process took about eight weeks, requiring
the Pumping Plant to be secured and dismantling, preserving
and storing tools and system control devices.
Since the project was shut down, the Pumping
Plant has been inspected periodically and maintained as insurance
against future flooding around the Great Salt Lake. It is
a permanent facility that cannot be dismantled for other uses.
