5.8.2 Wetland Restorations

ProjectLong Lake Wetland Restorations
DescriptionRestoration of drained or degraded wetlands in the Long Lake Creek subwatershed
Need

Two wetland projects in the subwatershed would be considered for restoration to restore hydrology, improve habitat, increase infiltration, expand wildlife corridors or connect other high-value resources. Prioritization and selection of specific restoration projects would be based on criteria including:

  • Potential to achieve multiple objectives such as improving downstream water quality, increasing infiltration, increasing stormwater storage, improving habitat, or connecting other resources
  • Opportunity to increase wetland acreage through restoration of drained wetlands

The following are some of the potential restoration locations that might meet those criteria, although other locations may also be considered.

Long Lake Creek Corridor: Several riparian wetlands downstream of Long Lake may be considered for improvement based on the results of the Tanager Lake diagnostic and. feasibility study. These wetlands may be a source of phosphorus and suspended solids to Long Lake Creek and restoration may address those export issues while enhancing habitat and vegetative diversity.

Dickey’s Lake Corridor: An 11 acre complex of Type 2 Manage 1 classification wetlands in the corridor between Dickey’s Lake and Long Lake have low vegetative diversity and impacted hydrology. Vegetative restoration of these wetlands with buffers could improve wetland functions and values and enhance the wildlife corridor between these two water resources.

Wolsfeld Woods West Side: A 13 acre Manage 2 wetland abutting Wolsfeld Woods to the west has low vegetative diversity. Vegetative restoration of this wetland with buffers could improve wetland functions and values and expand the wildlife corridor in this Key Conservation Area.

OutcomeRestored and improved wetland functions and values, enhanced habitat, increased infiltration, expanded and connected wildlife corridors, protection of downstream resources.
