Big Island Pond's Water Level is Regulated
of Big Island Pond Corporation's charter is to monitor and regulate the water
level of Big Island Pond. This is done at the dam located at the end of
Escumbuit Road in Derry, where our water empties into the Spicket River and
downstream into Arlington Pond in Salem.
water level is checked and tracked on a regular basis by a BIPC
representative, who works closely with the State of NH and Salem's Department
of Public Works to coordinate and regulate water flow. We try our best to keep our pond at a
consistent level of 8.5 feet as measured
at the dam. However, Mother
Nature occasionally has other ideas. No
one can accurately predicting the timing, duration, and intensity of rain
storms, and we appreciate your understanding that water levels will vary over
the course of a season.
Fall, the dam is opened slowly to lower the lake. This allows us to perform necessary
dam maintenance activities and gives residents, who have secured proper
permits, a chance to make repairs to their walls, docks, and other properties. Lowering of the water also offers a measure
of weed control if plants are exposed to sustained periods of hard Winter freezes.
the Spring, the dam is closed after the ice melts, and Big Island Pond refills
with water from underground springs and upstream brooks.
two weeks after the dam is opened in the Fall, volunteers perform annual maintenance
on and around the dam. Residents, families,
and friends are welcome to participate and learn more about the maintenance process.
