About the Long Lake Improvement and Sanitation Association
Founded in 1910, the Long Lake Improvement and Sanitation Association seeks to promote a clean and healthy Long Lake through water quality monitoring, fish stocking, dam and sluice gate maintenance, and other efforts. If you use the lake, please consider giving back by becoming a LLISA member.
One of LLISA's most important roles is maintaining the Long Lake dam, hoist, and sluice gate on Manitou Creek on the lake's west end. These three structures are important for maintaining the lake's water level, Chain o' Lakes access, and flood control. Read more about your dam here.
Long Lake is the terminus of the Manitou Creek Watershed. The Manitou Creek watershed is one of the largest watersheds in Lake County, with a total drainage area of 39.5 square miles (25,250 acres).
The Manitou Creek watershed contains a significant amount of water resources and public open space. Approximately 9,400 acres of wetland, floodplain, or public open space exists in the watershed. An additional 1,950 acres of property owned by the Lake County Forest Preserve District is located within the Manitou Creek watershed.
The watershed is currently experiencing rapid growth. Most of this growth will be in the Manitou Creek mainstem watershed that now is largely rural and agricultural land use. The population growth and the associated land use changes can have a significant effect on the watershed’s resources. Click here to learn more about the Manitou Creek Watershed.
