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 district was granted funds to purchase project materials. 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, in an effort to continue their conservation program
updated the WWDC Level I Report: Wind River Study: LeClair Canal and Riverton Valley
(Wyoming No. 2 Canal Rehabilitation), March 1993,with the Level II Report: Riverton Valley
Rehabilitation No. 2, Level II, October, 2001. The 2001 Level II Report recommended the
installation of pipe in nine additional open laterals and provided a revised estimate for
rehabilitation costs totaling $670,000. The 2002 Legislature appropriated $335,000 for 50% of
the project costs to be used for the purchase of materials. Engineering, installation and permitting
costs are provided by the district. Design and construction of two laterals, were completed during
the fall of 2002.
RECOMMENDED LEGISLATIVE ACTION:
No legislative action is required.
