The former Thirty Lakes Watershed District was established by order of the Minnesota Water Resources Board on May 18, 1971. After 45 years of natural resources conservation work, the Thirty Lakes Watershed District was disbanded due to the effort to reduce duplication of services, and lower residents’ future property taxes on July 21, 2016. Since then, Crow Wing County is holding these funds from the former Thirty Lakes Watershed District which are being used for water quality sampling for lakes in that watershed. The former District is located in west central Crow Wing County and covers approximately 70 square miles; approximately 60% is covered by surface water. The former District's major watersheds include: Clark, Edward, Gladstone, Horseshoe, Hubert, North Long and Pelican Lakes. The following communities and townships lie partially or wholly in the former District: The Cities of Breezy Point and Nisswa, Lake Edward, Center, Pelican and Mission Townships.
