Stillwater River (Maine)
The Stillwater River is an side channel of the Penobscot River in Maine. From its source in Old Town, the Stillwater runs northwest along the northeast side of Orson Island, the site of the Penobscot Indian Reservation. It then runs south along the west sides of Orson and Marsh islands, over three dammed falls. The stream rejoins the main stem of the Penobscot in Orono.
The University of Maine campus, including the Fay Hyland Botanical Plantation, overlooks the Stillwater River near its confluence with the Penobscot River.
