Constructed in 1963 by the USDA NRCS, this earth dam stands at a height of 15 feet and has a storage capacity of 130 acre-feet. Situated at the outlet of Fountain Lake, Bohn serves multiple purposes including recreation and has a normal storage capacity of 40 acre-feet.
Managed by the Wisconsin Department of Natural Resources, Bohn has a low hazard potential and a very high risk assessment rating. While the dam has not been rated for its current condition, it undergoes inspections every 10 years to ensure safety and compliance with state regulations. The dam features a controlled spillway type with a hydraulic height of 8 feet and a maximum discharge of 120 cubic feet per second.
Bohn's location in a high-risk area underscores the importance of proper risk management measures and emergency action preparedness. With the potential to impact downstream communities, the dam's owners and regulators must prioritize safety and regular maintenance to mitigate any potential risks associated with its operation.
