As mandated by the State of Maine, Little Sebago Lake will close the Hopkins Dam on April 15th to start to bring that lake up to its summer level. Some years ago an agreement was reached with the State to set the summer and winter water levels on Little Sebago Lake to settle disagreements among property owners. Since this is the upstream water source for Collins Pond, our dam will start to close a few days before this to bring our lake level back up to a normal summer level.
