Overview
SY LAKE
T17N, R21E, Sec. 11, Manitowoc County
Surface Acres = 16.6, S.D.F. = 1.40, Maximum Depth = 33 feet
Sy Lake is a hardwater, alkaline seepage lake with a surface area of 16.57 acres. It has both an inlet and an outlet, both of which are perennial. The outflow is also the beginning of Gooseville Creek. The lake has a maximum depth of 33 feet and a fishery consisting of largemouth bass, panfish and northern pike. In the past it has had a problem with carp and stunted panfish. Much of the shoreline (90%) is wild with 5 acres of adjoining wetlands, which may provide nesting areas for mallards and teal. There are 8 dwellings on this lake and no public access (WCD 1968). No recent water quality data have been collected for this lake.

Historical Description
Source: 1968, Surface Water Resources of Manitowoc County Sy Lake, T17N, R21E, Section Surface acres - 16.6, S.D.F = 1.40, Maximum depth = 33 feet A small, seepage lake located in terminal moraine. This lake has hard, light brown water and a mucky bottom. A small intermittent stream may drain the lake at the southwest end during periods of high water. Largemouth bass and northern pike provide fishing. Carp and stunted panfish are major use dwellings problems. More than 90% of the shoreline is wild and there are eight dwellings located on the lake. No public access is available. Mallards and teal may nest here, and a moderate number of waterfowl may utilize the area during the spring and fall migrations. Hunting is permitted.

Condition
Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water monitoring program uses a media-based, cross-program approach to analyze water condition. An updated monitoring strategy (2015-2020) is now available. Compliance with Clean Water Act fishable, swimmable standards are located in the Executive Summary of Water Condition in 2018. See also the 'monitoring and projects' tab.

Management Goals
Wisconsin's Water Quality Standards provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable
Management goals can include creation or implementation of a Total Maximum Daily Load analysis, a Nine Key Element Plan, or other restoration work, education and outreach and more. If specific recommendations exist for this water, they will be displayed below online.
Monitoring
Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy was recenty updated.

Watershed Characteristics
Sy Lake is located in the Sheboygan River watershed which is 260.12 mi². Land use in the watershed is primarily agricultural (47.30%), grassland (17.60%) and a mix of wetland (16.70%) and other uses (18.30%). This watershed has 340.24 stream miles, 4,345.33 lake acres and 27,968.05 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Available for runoff impacts on streams, Not Available for runoff impacts on lakes and High for runoff impacts on groundwater and therefore has an overall rank of High. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.However, all waters are affected by diffuse pollutant sources regardless of initial water quality. Applications for specific runoff projects under state or county grant programs may be pursued. For more information, go to surface water program grants.
