Delavan Lake Improvement Association
The Delavan Lake Watershed is 25 acres of land that drains into Delavan Lake. Our watershed drainage basin consists of all the land and water areas that drain toward Delavan Lake shown in green on the map. Because watershed awareness directly affects our lake, the  DLIA spearheaded a drive to raise monies to install 25 permanent signs along major roads around the watershed to help residents and visitors recognize that they are entering the Delavan Lake watershed.

The DLIA partners in the Healthy Lakes Initiative Program.

The Delavan Lake Improvement Association and Delavan Lake Sanitary District Partner in Healthy Lakes Initiative Program. Healthy Lakes Initiative is a statewide Department of Natural Resources program that offers grants of up to $1000 for best management practices installed by homeowners on their lakefront property. There are the five best management practices that homeowners can install with grant funding. Learn more...
The DLIA is actively working to protect the lake through the watershed.

The Delavan Lake Improvement Association is committed to providing financial support to farm conservation programs in the watershed.

In Managing the Water's Edge* case study on page 17, "...riparian buffers are capable of reducing large percentages of the phosphorous and sediment that are currently being carried by Wisconsin streams. Even in watersheds with extremely high loads (top 10%), an average of about 70% of the sediment and phosphorus can be reduced through buffer implementation."

Local farmers in our Delavan Lake watershed are invited to participate in conservation practices designed to plant buffer strips (cover crops) in key areas to slow down runoff into the watershed from their farm fields during storms and snow melts. The role of The Delavan Lake Improvement Association is to pay the land operator (farmer) for lost profits from taking the land out of production. This is typically done on a per acre basis renewed annually. To learn more about our current cover crop farm locations, click on this link.
