The Village of Grantsburg is sponsoring a project to develop a holistic management plan for Memory Lake and the Wood River.

The specific elements of the plan include:

1. Summary of historic information.

2. List of regulations/ordinances that affect Memory Lake.

3. Location and delineations of wild rice stands. Qualitative comparison of current aquatic plant species presence/absence and relative abundance to that of historic survey.

4. Comparison of fish communities above and below the Memory Lake dam.

5. Shoreline/watershed survey, including identification of ecologically sensitive areas and erosion areas with mapped and prioritized protection/restoration sites.

6. Wood River bedload and Memory Lake sediment core analysis, including location, type, and depth, and sedimentation rate and sources.

7. Definition/quantification of Memory Lake hydrology and hydraulics, including watershed delineations of Wood River, storm sewers, and overland flow.

8. Sedimentation modeling with suite of flows and loads under various dam operation regimes and restoration to channel flow.

9. Community survey and scoping/planning sessions.

10. Exploration of management alternatives and feasibility of each. Alternatives may include water level manipulation, dredging, non-point source control, and/or natural channel restoration.
