Welcome to the Green Lake Sanitary District

Our Mission:  To engage in activities that preserve, improve, and protect the natural resources of Big Green Lake and its Watershed.

 

The Green Lake Sanitary District, which is located in Green Lake County, Wisconsin, was established in 1964 and includes all of the existing areas around the lake (excluding the City of Green Lake).

The District was formed as a means to protect Big Green Lake and its associated resources with respect to sanitation and related land, air and water quality matters. In addition to coordinating solid waste collection in parts of four different Townships, the District also oversees the treatment of wastewater from approximately 1300 homes.

Of the Districts 2000 plus tax parcels, approximately 1000 of the 1400 homes are sewered with the remaining 400 homes being served by private onsite wastewater treatment systems.

Also included in the Districts umbrella of responsibility are programs associated with: Nonpoint Pollution Abatement, Aquatic Plant Harvesting, Lake and Watershed Water Quality Monitoring, Land Acquisition, Green Lake Fish Rearing Facility and General Administration.

 

Green Lake...Wisconsin's Deepest Inland Lake!

Located in beautiful Green Lake County, Wisconsin, Green Lake had its origin in a valley formed by a preglacial river. Glaciation deposited terminal moraines across the western end of the valley (along present-day Highway 73), which impounded the water and created the lake 12,000-23,000 years ago.

The Green Lake watershed encompasses approximately 57,000 acres. Silver Creek is the main tributary. Eight small streams also drain into the lake. The lake's outlet is the Puchyan River, which drains into the Fox River, and ultimately into Lake Michigan at Green Bay. A dam was constructed at the outlet in 1846 and increased the water level 5 feet by 1890.

Today, gates in the dam operated by the city of Green Lake control the water level. A regulation of the Department of Natural Resources specifies the maximum levels to be maintained in summer and in winter.

The sources of Green Lake's water, in approximate percentages, are: precipitation, 51%; surface water, 41%; ground water, 8%.
