The Shoshone Joint Powers Board requested assistance from the WWDC
for a comprehensive rehabilitation project. The Joint Powers Board
is made up of the Heart Mountain, Shoshone, Willwood, and Deaver
Irrigation Districts which serve approximately 93,000 acres.
The Bureau, in cooperation with the board and the WWDC, conducted a
rehabilitation study of the district's facilities in 1991, and
identified a number of major canals and structures in need of repair
or replacement. Many of the existing facilities are 80 years old.
The estimated total project cost is $15,000,000. Fifty percent of
the funds are being provided by the WWDC. The remaining funds are
being secured, as a zero interest loan to the board, through the
Bureau of Reclamation's Rehabilitation and Betterment Program.
In 1992, the project agreement was completed and executed and the
funding agreement with the Bureau of Reclamation was finalized. In
addition, the sponsor worked to develop the project work schedule,
as well as mitigation plans. In 1993, approximately 21,000 feet of
reinforced concrete pipe was manufactured. In addition, 15,000 feet
of pipeline was designed, approved and installed, including a large
diameter siphon. In 1994, approximately 35,000 feet of reinforced
concrete pipe and a large drop structure was installed; and grouting
of the Cedar Mountain Tunnel commenced. In 1995, 10,000 feet of pipe
and two large drop structures were installed and work continued on the
Cedar Mountain Tunnel. In 1996, 25,000 feet of pipe and two large drop
structures were installed and grouting continued on the Cedar Mountain
Tunnel. In 1997, 33,000 feet of pipe and three large drop structures
were installed and grouting continued on the Cedar Mountain Tunnel. In
1998, installation of 82,000 feet of pipe, one large drop structure, and
work on the flumed section of the Cedar Mountain Tunnel were completed.
In 1999, 103,000 feet of pipe and various canal structures were installed.
The Shoshone River Siphon was re-coated and a portion of the Heart
Mountain Canal was concrete lined. The Willwood Canal Gates on the
Willwood Dam were also rehabilitated. In 2000, the Buck Springs Creek
Siphon will be rehabilitated to complete the project.
