Lake Association & Township Lake and Watershed Management Plan

By July 27, 2012Water Resources

Lakeshore Environmental conducted a comprehensive lake study of a 286-acre lake located in Michigan to assist a Lake Association with the development of a long-term Lake and Watershed Management Plan. The lake contained over 25 acres of Eurasian Watermilfoil (Myriophyllum spicatum) and received external inputs of nutrients and sediments from the surrounding watershed. As a result of the study findings, the Lake Association considered a solution including the use of systemic aquatic herbicides, possible implementation of a lake-wide laminar flow aeration system and integration of watershed management practices. During the course of the study, Lakeshore:

  • Conducted whole-lake aquatic vegetation surveys of the lake to document the presence and relative abundance of aquatic plant native and non-native species
  • Evaluated the overall health of the lake ecosystem and trophic state
  • Addressed watershed land use issues such as erosion and sedimentation to improve water quality within the lake
  • Developed Best Management Practices (BMP’s) to help homeowners protect the lake
  • Investigated the feasibility of utilizing a whole-lake aeration system for improving water quality and reducing aquatic vegetation through reduction of sedimentary benthic carbon dioxide
  • Developed a 5-year financial budget for the local municipality and Lake Association to utilize for implementation of the suggested improvements
