The Delavan Lake Improvement Association was founded in 1895 and organized with this purpose: to help protect and preserve the lake and all land around it; to represent those who own its property, and to provide a wholesome and relaxing environment for our friends and visitors. Since then, the DLIA has maintained the primary focus of a ‘watchdog’ role, seeking to identify potential and existing issues that affect water quality and the long-term health of the lake. Additionally, it is our Association’s goal to forge strong ties with agencies such as the Wisconsin DNR, the U.S. Geological Survey, governing bodies at the State, County & Local levels, and other local & regional Lake Associations & Conservancies to help ensure timely attention to the condition and the needs of Delavan Lake.

We would welcome your participation and support as a member of the DLIA.
