Overview
Simpson Lake is a 13.1 acre spring lake that flows into Plumadore Creek which flows into Middle Inlet Creek. A study begun in 2006 to document changes to the shoreland area due to cutting of trees and shrubs and impacts from grading new developing lots has already noted losses to the shrub layer and ground cover vegetation. The parcels chosen for the study will continue to be monitored by the County in the future to further measure the impacts of riparian development on the local ecosystem.

Historical Description
A hard water spring lake having slightly acid, light brown water of moderate transparency. A dam adds about 6 head feet of water to this lake. The littoral zone is comprised entirely of muck. The shoreline is 70 percent upland, consisting of mixed hardwoods and conifers and 30 percent wetland of shrub bog. The fish population is reported to consist of trout, perch, bullhead and minnows. Waterfowl make limited use of this lake. There is no public access. Two dwellings are located on the shoreline. The outlet, Plumadore Creek, flows to Middle Inlet Creek.

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
Simpson Lake is located in the Middle Inlet and Lake Noquebay watershed which is 155.58 mi². Land use in the watershed is primarily forest (45%), wetland (34.60%) and a mix of agricultural (8.80%) and other uses (11.50%). This watershed has 145.85 stream miles, 3,254.49 lake acres and 28,278.00 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Not Ranked for runoff impacts on streams, High for runoff impacts on lakes and Medium for runoff impacts on groundwater and therefore has an overall rank of Medium. 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.
