PROJECT INFORMATION:
Flow measurements on the Riverton Valley Canal were conducted as part of the Wind River Basin
study. The Riverton Valley open laterals experience high exfiltration as well as high maintenance
costs. In 1994, the Commission recommended the project advance in the Rehabilitation Program to
Level III status with an appropriation of $350,000. This project addressed twelve laterals under the
main canal system. These open canals were replaced by buried pipelines, which greatly reduced
maintenance costs and water losses. The district prioritized system repairs and work was completed
in four phases from 1995 through the spring of 1999. The project appropriation served as a grant for
project materials, with payments only being made for materials invoiced to the district. The district
was responsible for all costs related to project design, permit procurement, land procurement,
construction engineering and construction of the project. A total of 12 laterals were rehabilitated over
a four year period from 1995 to 1999. The district has realized a 25% increase in delivery efficiency
with the improvements made to date.
The Riverton Valley Irrigation District would like to rehabilitate a number of their laterals in an
effort to continue their conservation program as specified in the WWDC Level I Report: Wind River
Study: LeClair Canal and Riverton Valley (Wyoming No. 2 Canal Rehabilitation), March 1993; as
updated by the Level II Report: Riverton Valley Rehabilitation No. 2, Level II, October, 2001. The
2001 Level II Report recommends the installation of pipe in nine additional open laterals and
provided a revised estimate for rehabilitation costs totaling $670,000. The district funding request of
$335,000 is for 50% of the project costs to be used for the purchase of materials. Engineering,
installation and permitting costs are provided by the district.
RECOMMENDED LEGISLATIVE ACTION:
The WWDC recommends the project be incorporated in the Rehabilitation program at Level III with
an appropriation of $335,000.
