Glen Lake is an 84-acre impoundment of Beaver Creek and has a maximum depth of 38 fget. The
lake, located in Glen Hills County Park, has a public boat landing and swimming beach. The dam
has a bottom discharge that provides some of the coolest summer stream water temperatures
recorded in the entire watershed. The lake is significantly affected by sediment and nutrient loading
from its watershed. Relatively hlgh levels of phosphorus and chlorophyll a were documented in the
1994 survey (Schreiber). Glen Lake experiences algal blooms and traps sediments originating from
streams feeding into it. Efforts to control runoff in the Glen Lake sub-watershed may reduce algal
concentrations and slow sedimentation of this impoundment (Engel).
An aquatic plant survey conducted in 1994 documented a moderately diverse population limited to
a narrow shoreline zone. The majority of plants are species tolerant of turbid water conditions
(Borman). A lake planning/protection grant would be useful for developing and implementing a
lake-specific management plan for resource management activities not included in the priority

Glen Hills Beach was assessed for the 2018 listing cycle; E. coli data sample data were clearly below the 2018 WisCALM listing thresholds for the Recreation use. This beach was meeting this designated use and was not considered impaired.

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 2016 . See also 'monitoring' and 'projects'.
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 and implementation of a Total Maximum Daily Load Analysis, habitat restoration work, partnership education and outreach and more. If specific recommendations exist for this water, they will be displayed below.
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.

Glen Lake is located in the South Fork Hay River watershed which is 181.99 mi². Land use in the watershed is primarily agricultural (60%), forest (29%) and a mix of suburban (6%) and other uses (5%). This watershed has 399.14 stream miles, 412.20 lake acres and 6,405.93 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.
