The public is invited to listen and learn from guest speakers Nicholas Macklem, Hubbard County environmental specialist, and Steve Henry, RMB Environmental Laboratories, at the Hubbard County Coalition of Lake Associations meeting. The presentations begin at 6 p.m. Thursday, Oct. 31 at the Northwoods Bank community room, Park Rapids.

Macklem will provide the current results of the county’s AIS program and plans. He will also cover supplemental funding for the watercraft inspection program, along with key dates for 2020.

Henry’s topic is “How Lakes Age: With or Without Zebra Mussels.” Over time, nutrients build up in lakes, causing changes to the lake bottom, aquatic plants, fish and water quality. Zebra mussels have not changed how fast nutrients accumulate in our lakes, but they have changed where nutrients are stored in the lake and how they are expressed. Learn new techniques researchers are using to track lake health.
