New Lake Management Plan Success

Rice Lake Situated in beautiful Northern Wisconsin has been harvesting fewer plants which in turn are producing clearer water and better water quality. How is that possible? Rice Lake Protection and Rehabilitation District, established in 1977 and making it one of the oldest in Wisconsin, has enacted a new management plan recommending the removal of invasive aquatic plants but not native plants.

The invasive plant not only affects populations of native plants, but has been known to impact fish by decreasing predator success, stunting fish year-classes and reducing spawning success. Curly-leaf pondweed grows in approximately 260 of Rice Lake's 936 acres. A goal of the management plan is to remove 80%, or 200 acres, of the curly-leaf pondweed annually while maintaining 40% of native aquatic plants like coontail and elodea.

Minnesota Aquatic Plant Control May Require Permit - Aquatic plants serve many important functions in lakes; they prevent shoreline erosion, stabilize bottom sediments, provide habitat for fish and wildlife, and tie up nutrients that might otherwise grow algae. The removal of too many aquatic plants can impair their ability to perform these important functions.
