Broad Bay is a 464-acre lake located in Carroll County in eastern New Hampshire, United States, in the towns of Freedom and Ossipee. Broad Bay is part of a chain of four lakes with identical water levels, due to a dam located downstream in Effingham Falls, New Hampshire. Upstream, a channel connects Broad Bay to Ossipee Lake, while a channel leads downstream through Leavitt Bay and Berry Bay to the start of the Ossipee River, which flows east into Maine and the Saco River.
