This agreement provides support to the state of new hampshire to implement its nonpoint source management program, focusing on watersheds with water quality impairments caused by polluted runoff from nonpoint sources. Nonpoint source implementation projects include a variety of structural and non-structural best management practices (bmps), watershed planning, monitoring, technology demonstrations, and a variety of education/outreach programs.activities:the proposed work in this agreement includes: * installation of best management practices (bmps) (estimated 10-20 projects) across several (eight) watersheds to reduce nutrient, sediment, and other pollutant loads to receiving waters. Often, these reductions are needed to reduce cyanobacteria blooms. * development of watershed protection plans to identify sources of pollution entering receiving waters and developing watershed protection plans to guide pollution reduction efforts. Watersheds targeted in this workplan include: * pine river pond * lake kanasatka watershed association * messer pond * little squam lake * tucker pond * province lake examples of the work being done in one of the watersheds, sunrise lake, are below. Declines in water quality have led to increased cyanobacteria blooms, including the most recent in june 2023 that spurred an increase in public awareness on water quality issues with residents and property owners around the lake, that require the reduction of phosphorus entering the lake from septic systems, stormwater runoff, erosion, and other sources. Watershed residents are concerned with the frequency and intensity of cyanobacteria blooms and acknowledge action is needed to reduce phosphorus inputs and thereby protect human health and preserve recreational uses of the lake. Four structural best management practices (bmps) are being proposed, including at two of the seven association-owned beaches and a shoreline buffer project with a partner that will be identified during the project. At hampshire shores beach, the proposal is to (1) install a rain garden with educational signage to treat stormwater. At sunrise lake lands association beach, the proposal is to (2) replace a culvert underneath lake shore road and (3) develop design and engineered plans to improve drainage and stormwater management. A (4) demonstration shoreline buffer project and associated outreach task will be conducted with assistance from the nhdes soak team. These projects will reduce total phosphorus loading to meet an in-lake concentration of nine micrograms per liter, reduce the frequency of cyanobacteria blooms, and meet water quality standards. The proposed non-structural BMP will be the development of a septic system regulation, as well as funding for additional bacteria sampling at the lake lands association beach.subrecipient:subrecipients will be carrying out the vast majority of the work, with nhdes oversight. In broad terms, that work includes, but is not limited to: * installation of best management practices (bmps) (estimated 10-20 projects) across several (eight) watersheds to reduce nutrient, sediment, and other pollutant loads to receiving waters. Often, these reductions are needed to reduce cyanobacteria blooms. * development of watershed protection plans to identify sources of pollution entering receiving waters and developing watershed protection plans to guide pollution reduction efforts.
