Fish and Aquatic Life
Overview
Lulu Lake is a natural lake managed for northern pike, largemouth bass, and panfish. This was once called Deep Lake since most of its basin is over 20 feet deep. The shores are entirely marshy save for a narrow gravel bank on part of the east shore. Access is afforded by the outlet channel which is navigable from Eagle Spring Lake and through a private campgrounds on the south shore. A trailer rental and one cottage are the only developments on the lake. A Milwaukee boys club maintains the northwest shore in its natural state. The 368 acres of equally woody and marshy wetlands adjoining its shore line classify this lake as aesthetically outstanding.

Recommendations
Monitor Water Quality or Sediment
Conduct water quality sampling on the Mukwonago River
Information and Education
Nature Conservancy interns in canoes will also intercept boaters utilizing the channel between Lulu and Eagle Springs and speak about reversing their motors to prevent the spread of exotic species
Map Invasive Species
Control Invasive Species
Worked to control Phragmites, purple loosestrife, reed canary grass, buckthorn, Eurasian water milfoil and narrow leafed cattail. Control methods include hand pulling, hand cutting, backpack chemical treatment and beetle rearing/dispersal.
Habitat Restoration - Shoreland
Walworth County will continue the Walworth County Lakes Specialist position for one year. The Lakes Specialist will provide educational information to lake residents regarding shoreline stabilization and shoreline restoration. The Lakes Specialist will also design shoreline restoration projects for interested landowners, provide technical assistance to contractors and hold workshops on shoreland restoration.
Protect Riparian or Shorelands
Walworth County will implement the Shoreland Protection Initiative project that includes: 1. A baseline lakeshore inventory; 2. ten lakshore demonstration sites; 3. the preparation of lake lawn and yard nutrient management plans; 4. fact sheets on lakeshore stabilization, shoreland buffers, shoreland regulations and lawn care; 5. an annual lakeshore inventory and distribution of shoreland regulation materials; 6. formation of a Walworth Co. Lakes Association and meetings with and newsletter pertaining to Walworth Co. lakes; 7. Workshops, information packets and news articles pertaining to the Fox river Basin Partnership Team Lakes Initiative; and 8. the formation of the Walworth County Land Conservancy.

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
Lulu Lake is located in the Mukwonago River watershed which is 86.21 mi². Land use in the watershed is primarily forest (28.40%), agricultural (22.80%) and a mix of suburban (16.90%) and other uses (31.90%). This watershed has 63.38 stream miles, 2,340.41 lake acres and 4,822.44 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, High 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.This water is ranked High Lake for individual Lakes based on runoff problems and the likelihood of success from project implementation.
