Little Robber Detention Dam Weakens Threatening Baggs Highway 789

The Bureau of Land Management (BLM) Rawlins Field Office (RFO) advises the Little Robber Detention Dam is weakening posing a flooding hazard to Highway 789, known as the Baggs Highway.

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 dam backs up the Little Robbers Gulch forming the headway to the Little Robber Reservoir. Failure of the dam could potentially submerge Highway 789, making the road impassible. No alternate route is available. The Little Robber Reservoir surface area is 28 acres with a storage capacity of 633 acre feet of water. No residences are threatened; however numerous gas wells are located in the area.

As of Monday evening, the dam’s principal spillway pipe is flowing full, eroding the back slope, and weakening the structure. The damage is due to separation of the corrugated metal pipe spillway. The detention dam was built in the 1940’s, repaired in 2005, and is maintained by the BLM. The RFO is coordinating with Carbon County emergency management personnel, the State of Wyoming, and local officials to develop an action plan.
