Home to one of the last remaining native sea-run brook trout fisheries in the eastern United States, the Theodore Lyman Reserve sits at the mouth of 4.5-mile-long Red Brook on Buttermilk Bay. Lyman is popular today with fly fishers, but catch-and-release only as The Trustees work to restore this treasured habitat.
Red Brook, the ecological, cultural, and scenic highlight of the reservation, is a 4.5-mile, spring-fed, coldwater stream that flows from White Island Pond to Buttermilk Bay. One of the few coastal streams in Massachusetts that supports anadromous fish (migratory fish which hatch in freshwater, make their way to sea to grow, and return as adults to spawn), Red Brook is home to one of the last remaining native sea-run brook trout fisheries in the eastern United States. It was one family's love for these "salters" that made the preservation of this special place possible.
In addition to Red Brook, the Lyman Reserve features freshwater wetlands, forested uplands, a sandy beach, and a scenic stretch of coastal shoreline with views of Buttermilk Bay and the Cape Cod Canal vertical lift railroad bridge.
