Whitmore Lake

This lake management project provides lake improvement to Whitmore Lake by controlling invasive and nuisance aquatic weeds.

The weeds are controlled by the application of special chemicals to the lake, followed by additional spot applications as necessary. The current lake management project is for a five year period (2018-2021).

The special assessment district for the Whitmore Lake Improvement Project is situated within Northfield Township, Washtenaw County, and Green Oak Township, Livingston County. There are 868 parcels located in the special assessment district.

Aquatic Plants

Aquatic plants are an important part of any lake or pond. They provide food and protection for fish, waterfowl, insects, mammals and microscopic animals. These plants also help replenish oxygen to the aquatic environment, critical for the survival of fish and other aquatic organisms.

However, aquatic plants can also become a nuisance. Invasive plants that are not native to Michigan can grow rapidly out of control, choking out other plants and organisms and reducing recreational options in the lake.

Starry Stonewort

Starry stonewort is one example of an invasive plant seen in Michigan waters. Click here to learn more about starry stonewort from the Huron River Watershed Council.
