Laws and Policies

In 2001, Governor McCallum created a Task Force on Invasive Species to evaluate and study the spread of invasive species in Wisconsin, to develop a statewide control plan, and to seek federal funding.

The group, co-chaired by Lt. Gov. Margaret Farrow and Rep. Dan Vrakas, issued its report and recommendations in February 2001.

Attention Boaters

Anglers should be aware of a change in state law that requires the removal of aquatic plants and zebra mussels each time a boat is put into state waters.

The new law allows game wardens or other state law enforcement officers to prohibit someone from placing a boat in the water if aquatic plants or zebra mussels are attached to the boat. Boaters who violate the new law also face a $50.00 fine for the first offense, and up to $100.00 for each subsequent offense within the same year. Read the Statute (exit DNR)
