Default Moultonborough Bay and Winter Harbor WQ Study Complete

The final Watershed Management Plan for the Moultonborough Bay and Winter Harbor subwatersheds has been completed and can be downloaded from our website.

If you were not able to attend the presentation of the plan on September 24th, a recording of it can be viewed here.

The Moultonborough Bay and Winter Harbor Watershed Management Plan study is the sixth water quality study that the Lake Winnipesaukee Association has been involved with. This stakeholder-driven process has proven successful in assisting communities around the lake in understanding how land use and development affects their local water quality, and provides communities, businesses, and residents with a road map and tools to achieve long term water quality improvement and protection.

Based on modeling and field surveying presented in the plan, both Moultonborough Bay and Winter Harbor are at risk for continued water quality degradation from future development under current zoning. The combined effects of increased development and climate change will likely continue to exacerbate the prevalence of potentially-toxic cyanobacteria in these waterbodies.

WATER QUALITY SUMMARY
• Current water quality at the deep spots in Moultonborough Bay and Winter Harbor is good and meets state criteria, except;
• Nuisance cyanobacteria blooms have caused the lake to be listed as impaired and Gloeotrichia blooms have occurred in Winter Harbor;
• A complex basin shape, mixing with the Broads, and nearshore inputs, can result in site-specific differences in water quality;
• Future threats to water quality could pose challenges for restoration.

PLAN RECOMMENDATIONS

The Action Plan focuses on five major topic areas that address nonpoint source (NPS) pollution, including:
• water quality monitoring,
• watershed and shorefront BMPs,
• roads,
• municipal planning and conservation, and
• septic systems.

Through the watershed survey, over 107 sites were identified in need of some type of mitigation or best management practice (BMP) to reduce pollutant loading to the lake. The BMP matrix prioritizes sites based on the estimated total phosphorus load reduction from the recommended BMP, cost, and observed site impact. From this list, contracting engineers at Horsley Witten Group visited the six highest priority sites and developed complete final designs for three sites.

Addressing all of the recommendations contained in the plan is a long term process and comes with a high price tag. However, not doing anything comes at an even higher price - the continued degradation of our water quality. Moving forward the Lake Winnipesaukee Association, in partnership with the communities and residents of Moultonborough, Tuftonboro, and Wolfeboro, will work to implement the actions identified in the plan with the goal of improving the water quality of the lake.
