Overview
Glen Lake, in the Mississippi River Watershed, is a 91.00 acre lake that falls in Grant County. This lake is managed for fishing and swimming and is currently not considered impaired.

Historical Description
A drainage and seepage-fed bay or backwater area of the Mississippi River adjoining Wyalusing State Park in the extreme northwestern corner of Grant County. Muck is the primary bottom type and average depth is about 7.5 feet. Northern pike, largemouth bass and panfish provide an excellent fishery and fishing pressure is quite heavy. Ice-fishing is popular on the lake in the winter. Winterkill has been an occasional problem in the past. The southern portion of the lake takes the form of a deep channel made when fill was taken to build a railroad dike following the eastern shore. Nearly 888 acres of wetland adjoin the lake on the north and west. A few ducks are usually seen on the lake and muskrat, mink, beaver, squirrels, raccoon, and deer are commonly found nearby. The park and the Upper Mississippi Wildlife Refuge provide 5.75 miles of public frontage. A boat landing in the park and one at Wyalusing also provide easy access.

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
Glen Lake is located in the Mississippi River watershed which is 110.47 mi². Land use in the watershed is primarily forest (37.70%), agricultural (19.50%) and a mix of grassland (18.70%) and other uses (23.90%). This watershed has 270.89 stream miles, 1,746.25 lake acres and 6,037.79 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Low 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.
