Billington Sea Your Pond, Your Responsibility

Billington Sea is a large (269 acre) shallow kettle pond formed by the glaciers as they passed through Massachusetts. Forested and other open space areas dominate the landscape of the 1,137-acre watershed, with residential development and commercial cranberry growing operation occupying the remainder of the watershed. Cranberry operations, runoff from residential land uses and septic system discharges all contribute nutrients and sediment to the pond.
Excessive inputs of phosphorus and sediment cause eutrophication - increased growth of nuisance weeds and algae and the accelerated filling in of a pond. Aquatic plants are an important part of a healthy pond ecosystem, yet too many plants or the invasion of non-native (exotic) plants can impair fish, wildlife habitats, and recreational pond uses.
