More money allocated for Great Lakes research

Michigan Sea Grant recently announced four new research projects with one common goal — protecting the Great Lakes. It committed almost $1 million to the projects, including $225,000 from the Department of Environment, Great Lakes and Energy. In addition, university research partners contributed over $500,000 in matching funds. Their major topics are water use, walleye, invasive mussel larvae and harmful algae blooms.

Projects aim to stop flooding of homes, businesses

The Great Lakes Water Authority plans to increase the ability of its water and wastewater systems to cope with flooding and other severe weather conditions under a capital improvement plan to be carried out over five years. The investment will consist of 182 projects from 2023 to 2027 in the region at a cost of approximately $1.73 billion.
