Bound by the Sandwich Range to the northwest and Ossipee Mountains to the south, the Ossipee Lake watershed is a subwatershed of the Saco River Basin and covers about 297 square miles across fourteen towns in eastern New Hampshire. FBE worked with the Green Mountain Conservation Group to develop watershed management plans for the Danforth Ponds and Lower Bays of Ossipee Lake (Phase I), as well as the Lovell River and the direct shoreline of Ossipee Lake (Phase II). The plans provided the Green Mountain Conservation Group with the tools needed to maintain the integrity of Ossipee Lake for future generations. FBE is now working with these partners on Phase III for Best Management Practice implementation in the watershed. The Ossipee Lake watershed contains New Hampshire's largest and deepest stratified-drift aquifer, which serves as the region's primary source of drinking water.
