Temporary Repairs Begin on Little Robber Detention Dam

The Bureau of Land Management (BLM) High Desert District and Rawlins field offices are beginning temporary repairs to the weakened Little Robber Detention Dam near the Baggs Highway 789.

A Rock Springs construction company has brought in two centrifugal pumps which will siphon 12,000 gallons of water per minute from the Little Robber Reservoir, which is backed up by the Little Robber Detention Dam. The pumps will release the excess water into the Little Robber Gulch lowering the waterline of the reservoir to below the damaged principle spillway. Once the water table has been reduced, alleviating pressure on the broken corrugated metal pipe, it will be banded back together. The plans will also require construction of a temporary road allowing access to the base of the dam. It should take approximately ten days to complete the temporary repairs. More permanent repairs are planned for later this summer.

Earlier this week, a break was discovered in the principle spillway causing erosion to the base of the dam, weakening the structure and posing flood warnings for the Baggs Highway, the primary road between Creston Junction, Wyo. and Craig, Colo. The Little Robber Detention Dam is located 13 miles north of Baggs, Wyo., approximately 2 miles west of Highway 789. The 55 foot high earth filled detention dam was built in the 1940’s, repaired in 2005, and is maintained by the BLM. The Little Robber Reservoir surface area is 28 acres with a storage capacity of 633 acre feet of water.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to sustain the health, diversity, and productivity of America’s public lands for the use and enjoyment of present and future generations. In Fiscal Year 2015, the BLM generated $4.1 billion in receipts from activities occurring on public lands.
