Lake Winnipesaukee Association – Love the Lake

The Lake Winnipesaukee Association (LWA) is a non-profit organization dedicated to protecting the water quality and natural resources of Lake Winnipesaukee and its watershed.  Through monitoring, education, stewardship, and science guided approaches for lake management, LWA works to ensure Winnipesaukee’s scenic beauty, wildlife habitat, water quality and recreational potential continues to provide enjoyment long into the future.

Our programs and projects arise from a deep appreciation and love for the lake and its environment, and desire to keep it beautiful and clean for countless generations to come. 

December 2017:  LWA has issued a Request for Qualifications to solicit professional assistance for development of a watershed plan for Moultonborough Bay and Winter Harbor, Lake Winnipesaukee.  For more information and to view the RFQ, click on this link.

The Lake Winnipesaukee Association (LWA) in partnership with the Town of Tuftonboro, will begin development of a watershed management plan for Moultonborough Bay and Winter Harbor, Lake Winnipesaukee, following our successful application for a Watershed Assistance Grant from the NH Department of Environmental Services with Clean Water Act Section 319 funds from the U.S. EPA.

This project builds on six years of effort by the Lake Winnipesaukee Association to develop a comprehensive lake-wide management plan for Winnipesaukee, and is a continuation of a community-based watershed planning effort to improve and protect all of the water resources within the lake’s watershed.  As a major economic asset and natural resource for the local communities as well as the State of New Hampshire, it is extremely important to assess the threats and issues affecting the lake’s health.

August 2017:  Stormwater Improvements completed at the Waukewan Bathhouse  

Lakes Region Public Access TV graciously videotaped our discussion and tour of the stormwater management practices installed to prevent the movement of sand and direct stormwater runoff to a treatment structure with an overflow to the catch basin.  UNH Stormwater Center provided the design which included a rain garden bio-retention basin, and replacement of the existing catch basin with a new deep sump catch basin with oil and floating debris trap. A NHDES Local Source Water Protection Grant  provided partial funding, along with the Town of Meredith, and the Windy Waters Conservancy.  The recommended best management practices will reduce the amount of pollutant loading to Lake Waukewan by an estimated 10.5 tons sediment, 8.9 lbs. of total phosphorus, and 17.9 lbs. nitrogen per year.  The video can be viewed here

Waukewan is a major asset for the Town of Meredith, both as a recreational resource and as the sole source for the municipal water system, serving approximately 3,000 residents and downtown businesses. But the lake suffers from elevated bacteria, cyanobacteria, low pH, and low dissolved oxygen. Led by the Lake Winnipesaukee Association, a group of local lake associations, residents, and community officials have worked with scientists and NHDES to develop the Lake Waukewan and Winona Watershed Restoration Plan (Lake Winona empties into Lake Waukewan by way of the Snake River). The plan, developed with the help of FB Environmental Associates and DK Water Resources Consulting is part of a long-term strategy to address water quality problems in both lakes by focusing on reducing sediment and nutrient loading to the waterbodies.
