The Saint George River is a river in Maine with a watershed of 225 square miles (580 km2) in a unique and historic area of mountains, sea coast, lakes, tidal streams and inlets. The origin of the Saint George River is the outflow of Saint George Lake (44°23′42″N 69°18′41″W / 44.3951°N 69.3113°W) in Liberty. The river follows a winding course 45 miles (72 km)[1] south to Thomaston, where the river flows into the estuary and runs about 12 miles (19 km) southwest to Muscongus Bay, forming the border between Cushing and St. George.
