The Iowa Department of Natural Resources administers the Low-head Dam Public Hazard cost-share program through its Conservation and Recreation Bureau, using funds appropriated by the Iowa General Assembly. The program addresses hazards created by low-head dams, including powerful recirculating currents that can trap and drown river users, while supporting compatible improvements to fish passage, recreation, and stream habitat.
For fiscal year 2027, Iowa DNR has prioritized funding for dam modification and removal. The cost-share application also describes categories for warning signage and portage trails, exploratory studies, engineering, and construction. These categories support different stages of mitigation, from gathering information and engaging communities to designing and implementing changes at hazardous dams. Iowa DNR separately offers technical assistance to dam owners and their partners.
