The Songo River in Naples, one of Maine’s busiest waterways, is 3.1 miles long and connects Long Lake and Brandy Pond with Sebago Lake. Separating the upper and lower river is Songo Lock, the only remaining operational lock of the Cumberland and Oxford Canal. The lock was completed two years before the Town of Naples was incorporated in 1834.
The Songo River is a thoroughfare for fish as well as boats. So the list of fish in the Songo includes all fish that frequent Brandy Pond, Long Lake and Sebago Lake, even though they may not be resident year-round. Smallmouth and largemouth bass provide the most significant fisheries. Brook trout are stocked in the river. Large numbers of white perch are present in Brandy Pond, but due to their abundance, they are generally small in size and not attractive to many anglers. They also compete with most other species for both food and space which tends to limit the potential of other species, particularly salmon, trout, and smelt.
In 2012, the first survey of Brandy Pond revealed only a few dozen plants in four locations. Except for one medium-sized patch, which has already been removed by the LEA crew this spring, the upper Songo River is clean of milfoil. With the use of extensive bottom barriers and suction harvesting, the crew has also cleaned out the lower river from the lock to the ranger station.
