2020 Lake Sunapee Watershed Management Plan (WMP)

LSPA updated its existing 2008 WMP to satisfy all nine elements required by the Environmental Protection Agency (EPA). This plan addresses ways to improve current water quality in the face of many challenges including continued development and more frequent severe storm events due to climate change. Included in the plan is:

1. A 10-year water quality goal established to reduce phosphorus loading into Lake Sunapee.

2. Proposed best management practices designed to address areas of concern identified from a watershed survey.

3. An Action Plan created to meet the aforementioned water quality goal. The plan is divided into the following categories: Education & Outreach, Research, Further Evaluation, Monitoring and Assessment, Land Conservation, Land Use Regulation, Zoning and Ordinances.
