The TriTown Forest Preserve borders on 76 acres of Avalonia-owned open space in Griswold and abuts over 800 acres of conservation easements held by The Nature Conservancy. A 213-acre section of the Pachaug Forest owned by Connecticut DEEP is across the street from TriTown, and the 24,000-acre Pachaug Forest connects into Rhode Island’s Nature Conservancy Borderlands Project. The Forest protects the headwaters of Miller Brook and Broad Brook (the latter stocked regularly by CT DEEP with brook trout and brown trout) which flow into the Quinebaug River, the Shetucket River, and on to the Thames River, forming part of the Thames River Basin of The Last Green Valley, a National Heritage Corridor.
