USGS tests potential sites in St. Clair River for new spawning reefs
Sturgeon, officially classified as threatened in Michigan, are the dinosaurs of the Great Lakes, with their dramatic armoring and slow maturation rates, growing as long as six feet in length and living as long as 150 years in the case of females, which spawn every four years. The USGS has had its eye on the Hart Light site for a while. But the agency’s models – which emphasize river flow and depth – only recently identified Courtright as a potential reef site, said Ireland. The Courtright and Hart Lights are on the Canadian side of the river, but the reefs would be constructed in U.S. waters. continued
