The Lake Management Plan for Pewaukee Lake (the Plan) is the third comprehensive management plan for this Lake and was developed to provide a set of targeted, specific recommendations to improve Pewaukee Lake, its tributaries, and ecological conditions throughout the watershed. This Plan supplements and builds upon previous plans and recommendations, such as the 1984 and 2003 lake management plans (see sewrpc.org); the 2017 aquatic plant management plan; and studies by the Wisconsin Department of Natural Resources (WDNR), the United States Geological Survey (USGS), and Wisconsin Lutheran College (WLC). Many recommended management measures from the previous editions of this Plan, such as educational programming, acquiring wetland parcels, promoting native aquatic species, and enhanced water quality monitoring, have been incorporated into past and ongoing Lake management practices.

The Lake Pewaukee Sanitary District will hire a contractor to analyze plant survey data collected in the summer of 2011, update the aquatic plant management plan and add two elements to the lake management plan. The final report will contain the following elements: 1) Results of the points sampled, including sediment type found and maximum rooting depth; 2) Results of a general lake survey to map general plant beds, map localized plant beds, map species distribution and a list of plant species found; 3) a table denoting number of sites found for each plant species, overall % frequency, % relative frequency, average density, and relative density; 4) maps showing the lake wide point intercept density for each exotic aquatic plant and the top 5 native aquatic plants; 5) results of the study of possible water level manipulation for the benefit of fish spawning; 6) identification of additional offloading sites with a discussion of feasibility; 7) identification of wetlands and critical sites for future acquisition; 8) results of the water chemistry comparison between the east and west basins of Lake Pewaukee; 9) a discussion of alternatives for aquatic plant management; 10) results of a flow quantification study for stream inlets into Pewaukee Lake; and 11) a summary of 3 public meetings to discuss the update of both the aquatic plant management plan and the lake management plan.
