One of the goals of the Lake Improvement District is to promote the reduction of non-native aquatic invasive species. Aquatic invasive species are non-native plants, animals and other organisms. When they are introduced into a lake or river they cause harm to the ecosystem. Once in a lake or river they can be impossible to eliminate and difficult to manage.
The Lake Improvement District actively works to minimize the spread of aquatic invasive species by conducting boat inspections at public water accesses. The Lake Improvement District also provides cost share funds to lake associations for treatment of Eurasian Water Milfoil and Curly-leaf Pondweed to improve navigation.
