MARQUETTE, MI – (Great Lakes Radio News) – The State of Michigan will partner in an effort to construct a new sea lamprey barrier in Manistique on the Manistique River.
During a stop in Manistique today, Governor Rick Snyder announced the new barrier will be constructed by the U. S. Army Corps of Engineers and financed by the Great Lakes Fishery Commission.
The existing dam, owned by Manistique Papers, Inc., once served as an impediment to migrating sea lampreys, but is now more than 100 years old and deteriorating. Sea lampreys now have free access to the entire Manistique River, a huge watershed covering more than 3,600 miles.
Sea lamprey numbers in Lake Michigan have increased dramatically in recent years because of access to the Manistique River system.
At an estimated cost of nearly $750,000 to treat and kill sea lampreys every two years in the river, this project will produce significant cost savings over time. This project will also replace an aging water line critical to the City of Manistique and upgrade the city’s flood control wall.
