Begin Date: May 2014
Completion Date: August 2014
IDNR Involvement: $35,112 Mitigation Grant
A project to convert a former low-head dam into a small rock-arch rapids was completed in August, 2014. The project improved fish passage, navigation opportunities, angling access, and helped to stabilize eroding bluffs and create fish habitat upstream with three j-hook vanes. Iowa DNR supplied $35,112 in dam mitigation grants, and DNR mitigation staff assisted with project management, design, and construction supervision. Citizen donations and city funds covered the remainder of the $70,000 total project cost.
