In the late in 70s and 80, the US Army Corps of Engineers completed a major flood control project in Minot by channelizing the Souris River and eliminating the winding nature. As a result, “dead loops” were created with control structures on each end and low head dams between the structures so water could still flow through the dead loops when gates are opened. There was also a low head dam constructed by the Minot Water Treatment Plant to hold a pool of water to ensure raw water supply during low water conditions. Due to the 4’-6’ drop-off over the dam, under currents (called a roller effect) create human safety risks. In 2020, the ND State Water Commission assessed low head dams across the state and a few of the structures in Minot made the priority list. The Minot Water Plant low head dam has the highest hazard prioritization in the state.
1. Recommend council approve a budget amendment to allocate funds to begin design work for the low head dam remediation project.
