A rain garden skirted with an infiltration trench designed to capture storm runoff from a gravel road before it entered Ossipee Lake was installed by volunteers at Camp Calumet in August of 2019. Designs such as this capture phosphorus and nitrogen present in sandy non point source pollution. The reduction of these nuturents will help to prevent cyanobacteria and algae blooms in peak summer temperatures.
GMCG aims to install at six to eight such BMPs by the end of 2020 on areas directly affecting Ossipee Lake. These projects serve as showcase examples that the greater lake community can duplicate at their own properties.
BMPs are not only improve water quality but the landscaping techniques used to build them often improve the aesthetics of a property as well!
Funds for this project are provided in part by a Watershed Assistance Grant from the NH Department of Environmental Services with Clean Water Act Section 319 funds from the U.S. Environmental Protection Agency.
