Climate Change Leads To Less Lake Ice
Grand Traverse Bay was one of 122 lakes worldwide included in a new study on disappearing lake ice. Researchers at York University in Toronto looked at nearly 80 years of lake-ice data from the National Snow and Ice Data Center, and counted the ice-free years. (If a lake did not have 100% ice cover for at least one day, the researchers considered it an ice-free year. The study did not account for the thickness or duration of the ice.) They found the number of ice-free winters among the lakes had more than tripled since 1978.

Lost lake ice can have far-reaching ecological, cultural and economic impacts. Winter recreation activities like ice fishing derbies and ice festivals are an economic boon for many lake communities, for instance, and lakes without ice have more waves through the winter, leading to shoreline erosion. Lakes are also warmer in years without ice cover, making them more prone to toxic algae blooms that can harm fish, pets and people.

Aquatic Weed Harvesting Update - The lake weed harvester began operation for the season on May 4th. This year it has been operating five days a week, with some of those days having extended hours. To date, 382 cubic yards of aquatic plants have been removed from the lake...which is 64 truckloads of lake weeds disposed of just this year! During the same period last year, 94 cubic yards of aquatic plants were removed from the lake.
