112.PROJECT:Wheatland Sand Lake Dam/Cañon Canal Rehabilitation
SPONSOR:Wheatland Irrigation District
LOCATION:Carbon County
Purpose Chapter Session Account Appropriation Due Date
Level I 15 1996 I $200,000 1998

The Wheatland Irrigation District serves approximately 55,284 acres and 911 water users. The Wheatland Irrigation District assesses $9.50/acre. The Wheatland Irrigation District operates Sand Lake and the Cañon Canal as a part of their water supply and storage facilities. Sand Lake stores 1105 acre feet of water with a 1953 priority date. Water is released from Sand Lake into Rock Creek downstream to the diversion headgates of the Cañon Canal. The water is transported down the Cañon Canal to King Reservoir, and released from King Reservoir into Dutton Creek. From Dutton Creek the water is diverted at the headgates of the Dutton Canal to the Laramie River near Bosler. The Laramie River conveys the water to either Wheatland Reservoir #2 or Wheatland Reservoir #3 where it is stored until irrigation calls are made. Water is then released down the Laramie River to the Tunnel Diversion and carried via tunnel into Bluegrass Creek where it is diverted for irrigation use in the vicinity of Wheatland.

In May of 1995, the emergency spillway of Sand Lake became clogged with ice and snow. Because of the isolated, high altitude location of the reservoir, the Wheatland Irrigation District was unable to bring equipment in to clean the spillway. Extremely high precipitation during April and May 1995 resulted in reservoir inflows that could not be bypassed by the outlet works and the embankment was overtopped resulting in a partial collapse of the embankment. Fortunately, riprap placed on the upstream face of the dam was not washed through the breach and saved much of the embankment. At present, the condition of the dam will not allow water to be stored.

During the spring of 1995, unprecedented precipitation caused an active landslide near Arlington, Wyoming to slip down slope at an accelerated rate and breech the Cañon Canal. The canal conveys approximately 185 cfs and traverses the slide. The WID is rebuilding the canal but further mass movement will cause canal failure again. The landslide needs to be stabilized, or the canal rerouted to prevent further failures. Adjudicated water rights out of Rock Creek and Sand Lake storage water cannot be reliably conveyed to Wheatland Flats until the canal is repaired and/or the alignment changed. The Level II analysis of the Sand Lake Dam and the Cañon Canal commenced in 1996 and is in the process.

In 1997, the Level II project was completed. The alternatives selected for Level III include the reconstruction of Sand Lake Dam and placing an emergency spillway on the center of the dam, fixing the outlet pipe on Dutton Reservoir, repairing the landslide area above the canal and making repairs on the canal system. Conceptual designs and cost estimates were prepared on these alternatives. The cost estimates showed the total project cost to be $455,000.

The WWDC recommends the project be advanced to Level III status in the Rehabilitation Program, with a 1998 appropriation of $475,000. The financing plan includes a 50% grant for $237,500 and a 50% loan for $237,500 at 6.00% for 25 years.
