The first of nine rock reefs is under construction in the St. Clair River delta northeast of Detroit. The goal of the project, which is led by Michigan Sea Grant, is to boost populations of lake sturgeon and other rare native fish by providing river-bottom rock structures where they can spawn. The rock reefs are designed to assist several native species that are considered threatened or endangered in Michigan, including lake sturgeon, mooneye, the northern madtom catfish and the river redhorse sucker. Walleye, a popular sport fish, and commercially important lake whitefish should also benefit. The new reefs will be constructed in the Middle Channel of the St. Clair River delta, near an existing lake sturgeon spawning site.

Michigan Sea Grant has been awarded more than $1.5 million from the federal government to lead two Great Lakes restoration projects that will restore native fish habitat and help clean up marinas across the region. It will also assist on five federally funded projects focused on issues including endangered fish, beach contamination, sound boating practices and marina operations, and water pollution.

Michigan Sea Grant today awarded a total of $409,417 to researchers from three Michigan universities. The research will focus on Michigan's coastal and Great Lakes issues involving wind power and restoring natural river flow in the Clinton River watershed. The funding will sustain three-year research projects and is contingent upon annual appropriations from Congress. The grant funds are leveraged by an additional $254,457 from non-federal sources, including state and university partners.
