Flow measurements on the Riverton Valley Canal were conducted as part of
the Wind River Basin Study. The data generated in this study process
identified the high loss areas of the canals and estimated the losses.
The district requested that an assessment of the laterals under the
canal be conducted. The proposed Level III project will address seven
of the laterals under the main canal system.
The Riverton Valley laterals experience areas of high exfiltration as
well as being high maintenance cost areas. Some of these laterals run
for extended distances through the City of Riverton and are difficult to
access and maintain. These presently open canals will be replaced by
buried pipelines. This will greatly reduce both maintenance costs and
water losses. The estimated total project cost is $700,000.
In 1994, the Commission recommended the project be progressed in the
Rehabilitation Program to Level III status with an appropriation of
$350,000. The project appropriation would serve as a grant for project
materials. Payments will only be made for materials invoiced to the
district. The district would be responsible for all costs related to
project design, permit procurement, land procurement, construction
engineering and construction of the project. The district has
prioritized the system repairs and work was completed in the spring and
fall of 1995. Work will continue, using district labor and equipment,
in 1996 and 1997.
