Watershed Management Plan

Conesus Lake was added to New York State’s 303(d) list of impaired waters for phosphorus impairment in 2002 followed by a listing in 2006 for dissolved oxygen impairment. The Conesus Lake Watershed Management Plan was approved in 2003 to guide the implementation of water quality improvement projects throughout the watershed to address the 303(d) list impairments. The plan delineates water quality improvement projects into key recommendations. Each year the Conesus Lake Watershed Council publishes an Annual Report Card which tracks recommendation implementation progress and associated water quality monitoring efforts.  

Implementation

Implementation projects range from zoning updates and invasive species prevention to shovel in the ground streambank and road ditch remediation.

Water Quality Monitoring

The framework in the Management Plan calls for a three-year rotation among lake monitoring, watershed-wide monitoring, and specific stream segment or subwatershed monitoring. The framework was crafted to balance resources between the lake and watershed. Monitoring tracks the progress and effectiveness of the implemented watershed management plan recommendations.
