MAD Scientist Associates LLC (MAD) was proud to assist the City of Delaware and other partners to continue the important work of restoring the Olentangy River. Twenty-two miles of the Olentangy River are designated as State Scenic River, but much of the waterway has been impacted by rapid urbanization and hydro-modifications. MAD was contracted to conduct mussel surveys and obtain a permit from the U.S. Army Corps of Engineers for the removal of two low-head dams just upstream of the State Route 23 bridge. A Nationwide Permit #27 for Aquatic Habitat Restoration, Establishment, and Enhancement Activities was received this past spring. In preparation for demolition activities, mussels in the work area were relocated and, during low flow summer conditions,the dams were successfully removed. The river has since returned to a more natural flow regime, with expanding beds of water willow and free-flowing riffles and runs providing valuable in-stream habitat. We commend the City of Delaware for taking on this project. We were pleased to play a small role in the restoration of one of Ohio’s beautiful rivers and we look forward to similar opportunities in the future!
