A new study suggests raising the water level in Lake Huron could cause as many problems as it solves.
Eugene Stakhiv is U.S. Co-chair of the International Great Lakes Study.
He says people could build dams or other structures in the St. Clair River to slow the flow of water out of Lake Huron.
That would raise the level of Lake Huron and benefit marinas and wetlands around the lake.
But water levels would also rise near Chicago, which already has high lake levels.
