Little Long Pond in Plymouth, Massachusetts is a 45 acre kettle pond located in the south-central part of the town. It is a shallow pond with an average depth of 5 feet, a maximum depth of 8 feet, and with steep sides on the west, north and east. The pond is situated in a rural residential zone, where it is bordered by dense woodland to the west and by dense residential development to the north and the east. To the south is the parking lot for the state boat ramp at Long Pond, and a scout camp borders the south-west shore. The relatively dense residential development, which presently contains over 100 homes within a 1,000 foot radius of the center of the pond, has substantially fragmented the vegetated buffer zone around the pond and is certainly contributing nutrients to the pond. Little Long Pond continues to be ultra-eutrophic, and no apparent corrective actions have been taken since Lyons and Skwarto identified the water quality problems back in 1980. The water quality appears to be getting worse today, as nutrient levels frequently exceed those of 1979 and 1980. The largest area of altered landscape is residential development, and it is here where most efforts must be made. All stakeholders must do their parts to minimize their impacts on this pond, for it continues to feel the effects of high nutrient loading even though it has a moderately rapid flush rate of 18 days. The state must also do its part to maintain the parking lot for the Long Pond boat ramp so that it doesn’t contribute additional influxes of nutrients from parking lot runoff. But, as the need to rehabilitate the pond gets more acute, it will be up to everybody to reduce their personal impacts on the pond.
