The Bureau of Indian Affairs, U.S. Army Corps of Engineers, and other entities have been meeting with the Fort Belknap Tribe about the potential for flooding on the reservation if the Bureau of Land Management (BLM) Dam, BR-12, on 15 Mile Creek were to fail. Due to snowmelt and spring runoff the reservoir is full and some internal erosion of the earthen dam has taken place. BLM engineers and contractors are working to mitigate the problem.
