Introducing the Gateway

Welcome to the Winnipesaukee Gateway– Your “one-stop shopping” source for maps, environmental plans,  water quality data, recreational opportunities, and more!

We invite you to check out some of the cool features of the site such as the Monitoring Sites Map for lake data, the Stormwater Footprint Calculator, and the Map Atlas. New information and features are always being added, so check back often, and let us know what you think.

The Winnipesaukee Gateway was created to house the Lake Winnipesaukee Watershed Management Plan.  Management Plans are being completed on a sub-watershed basis. Explore the Management Plan tab for more information.

On April 5, 2018, the Wentworth Watershed Association is hosting a 2 hr information session from 5-7pm at the Wolfeboro Town Hall on landscaping best practices that professionals and homeowners can do that will help protect our lake from polluted stormwater runoff.  Small bites and local beer will be served.  Contact the Wentworth Watershed Association to register.

Check out the completed study to address water quality impairments in the Moultonborough Bay Inlet area of Lake Winnipesaukee.   The Watershed Restoration Plan provides a roadmap for preserving the water quality of MBI, which historically has exhibited high concentrations of in-lake phosphorus, and excessive milfoil growth.
