Location: Roscommon County
Project Status: Current
- Involve stakeholders in discussions to determine concerns with removing the Higgins Lake dam.
- Determine the extent to which the Cut River’s flow capacity is restricted by road crossings, culverts, or other structures.
- Estimate the original bottom elevation of Higgins Lake at the discharge into the Cut River (currently rock fill covers the area).
- Estimate Cut River flows and Higgins Lake surface water levels and annual fluctuations under normal, dry, and wet conditions.
- Estimate how changes in Cut River flows will affect downstream areas.
- Evaluate potential shoreline habitat (wetlands, vegetation types, gravel bottom, etc) gains or losses in Higgins Lake under variable surface water level conditions.
- Evaluate shoreline erosion potential in Higgins Lake under variable surface water level conditions.
- Evaluate navigation and boat dockage changes under variable surface water level conditions, including boat ramps and marinas and potential needs for dredging and dock extensions.
- Evaluate expected changes in groundwater levels under the proposed new variable surface water level conditions.
- Evaluate likely impacts of the dam removal on lake and river fishery resources.
