Lake Management Plan
The Lake Management Plan, as presented below, was approved by the WDNR in April 2026. The management plan is used when applying for permits and grants to do conservation and project work. The plan also helps property owners understand the lake, its attributes, and how to steward it effectively.

The plan focuses on preserving the lake’s health improving water quality controlling invasive species. Key components include:
- Aquatic Invasive Species Management: prevent further infestations through watercraft inspections, volunteer and professional monitoring, and targeted control measures like hand harvesting and herbicide treatments.
- Water Quality Protection: maintain current conditions through regular monitoring phosphorus reduction efforts for example beaver dam removal and stakeholder education on blue-green algae blooms.
- Navigability Improvements: support responsible mechanical harvesting to manage nuisance aquatic plant growth and ensure access to open water areas.
- Stakeholder Engagement: Educate lake users through newsletters, social media and surveys, while fostering partnerships with local and state organizations to enhance lake management.
- Ecological Enhancements: Promote shoreland restoration, protect natural shorelands, expand fish habitat with coarse woody debris projects, and continue winter aeration to support a healthy fishery.
History of Proactive Management of our Lake
The first comprehensive lake management plan for Little St. Germain Lake was developed in 2004 as part of a community-wide project sponsored by the Town of St. Germain Lakes Committee. It was intended as a five year plan. Advances in how to better manage Wisconsin’s lakes were made between 2004 and 2009, particularly in regard to aquatic vegetation. With new WDNR statewide standards in place, the board of commissioners worked closely with consultant, Onterra, LLC of De Pere, WI to update the 2004 plan. The December, 2010 version of the plan is available here: 2010 Management Plan and Appendices A-F, Appendices G-L. The 2019 version of the plan is available here: 2019 Final Lake Management Plan and 2019 Plan Maps plus 2019 Plan Appendices.
