Aquatic invasive species threaten Wisconsin's lakes, rivers and wetlands. They disrupt the natural balance of species in our waters and can take the fun out of boating, fishing, and swimming. Getting out on the water is an integral part of Wisconsin life and lakes are the economic engines of many rural counties and urban waterfronts. I am proud to report on the hard work of many committed volunteers and partners. Wisconsin has made significant progress in its efforts against unwanted invaders during 2010-2011. The plan for protecting the waters of Wisconsin is straightforward, and is implemented in a variety of ways by volunteers and staff in communities across the state.
