Little Robber Detention Dam Condition Upgraded

The Bureau of Land Management (BLM) Wyoming State Office and Rawlins Field Office engineers are upgrading the condition of the Little Robber Detention Dam near the Baggs Highway 789 to weakened, but stable.

The BLM engineering team, construction contractors, and emergency personnel are inspecting the damage to the dam caused by a break in the joint of the corrugated metal pipe principle spillway which is eroding the base, weakening the structure. Warmer weather has also increased spring run-off on the Little Robbers Gulch, elevating the water level in the Little Robber Reservoir, the headwaters of the dam. Repair options are being evaluated, including bringing in pumps to reduce the reservoir’s water table, thus alleviating pressure on the pipe by releasing the overflow into the draw. Even though the integrity of the dam is compromised, crews believe it will hold until repairs can be completed.

The Little Robber Detention Dam is located 13 miles north of Baggs, Wyo., approximately 2 miles west of Highway 789, the primary road between Creston Junction, Wyo. and Craig, Colo. 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 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.
