Description
The Iowa Department of Natural Resources’ Low-head Dam Public Hazard Program helps dam owners reduce hazards on navigable streams in Iowa. Low-head dams can create recirculating currents that trap and drown river users while also blocking fish movement. For fiscal year 2027, Iowa DNR has prioritized funding for dam modification and removal to address both concerns.
The broader cost-share program also covers warning signage, portage trails, exploratory studies, engineering, and construction. Its goals bring public safety together with fish passage, recreation, and stream habitat restoration. The program is administered by Iowa DNR’s Conservation and Recreation Bureau under Chapter 30 of the Iowa Administrative Code, using funds appropriated by the Iowa General Assembly.
