Tip of the Mitt Watershed Council conducted a 2022 Shoreline Survey of Larks Lake with funding from the Larks Lake Association. The Watershed Council circumnavigated the entire Larks Lake shoreline on kayaks to document signs of nutrient pollution (algal growth), habitat loss, and shoreline erosion. 


Greenbelts are a natural buffer of native vegetation between the water’s edge and your lawn that helps to reduce erosion by stabilizing the soil, filtering nutrients and other pollution. Greenbelts can also deter geese who prefer well-manicured lawns and unrestricted access to the water.

Cladophora Density

Cladophora is an algae that grows as a film and in later growth stages as filaments on hard substrate near the shoreline. Increased nutrients, such as phosphorus from failing septic systems, enhance Cladophora growth to abnormal levels. Monitoring Cladophora serves as a useful bio-indicator of changes to nutrient inputs near the shoreline.
