Milo is the largest town in the Three Rivers Community. It is also the second largest town in Piscataquis County. Milo contains the three rivers of the community which are the Piscataquis River, Sebec River, and Pleasant River. The Sebec River flows through the center of Milo. Just before it goes under the West Main Street bridge, there are a set of falls with a dam sitting atop them. These are known as Trafton's Falls, named for Mark Trafton who rode a raft over them.
