About Pearly Pond
Pearly Pond is a 191-acre lake in Rindge, NH. Most of the watershed for Pearly Pond is undeveloped.(click here for a map of the watershed). Franklin Pierce University, and 52 residences are located near the lake. It is a shallow lake, only 17 feet deep at the deepest point, and averaging 7 feet deep. There is no public boat access. The Franklin Pierce beach is open to the public and there is a lifeguard on duty from noon to 5 on most summer days. It supports a variety of warmwater fish, including largemouth bass, chain pickerel, yellow perch, pumpkinseeds, horned pout, and others. Turtle species commonly seen in the lake include snapping turtles and Eastern painted turtles. Wood turtles are found in the area but not commonly in the pond. Otter, beaver, mink and other wildlife species are also common. At least 72 species of birds have been seen on or near the pond, click for a list of the Birds of Pearly Pond (compiled by Dr. Bill Preston).

History of Pearly Pond
What do we know about water quality in Pearly Pond?
The amount of pollutants and the general health of the lake have been monitored by volunteers from the Pearly Pond Association, through the NH Volunteer Lake Assessment Program (VLAP) since 1992. The following is an excerpt from the 2012 VLAP report for Pearly Pond.
What are some possible sources of pollution, and some potential solutions?
Students at Franklin Pierce researched a few areas on campus and identified some potential problems, as well as recommended solutions. Click on the links below for a visual representation of their results and recommendations.
The Milfoil Problem
Pearly Pond has several infestations of the invasive plant, variable leaved milfoil, Myriophyllum heterophyllum. This plant is an exotic plant that has no native predators to keep it under control. If left unchecked, it will grow so much it could outcompete native species, decrease fish habitat, and lead to tangled, unpleasant recreational experiences for boaters and swimmers. The Pearly Pond Association has worked with the NH Dept. of Environmental Services to keep these patches from spreading.
