Gatehouse Property Sediment Basin
Lake Saving Project Summary Sheet
Gatehouse Property: Sediment Retention Pond - 2006
The Gatehouse property in-stream
sediment pond, after being delayed a
year due to wet weather, was completed in September of 2006 and is
located on the Gatehouse property adjacent to the Melody Manor Resort off
of Rt. 9N along Huddle Brook.
It is an in-stream basin and was designed with a storage capacity of approximately 350 cubic yards. The
new basin has dimensions of 45 feet in
width and about 100 feet in length.
The entry and discharge transition
zones are stone lined to connect the
basin with the gravel bed of the original stream. The bottom of the pond is
unlined to allow for periodic dredging
of the pond. Both sides are lined with
riprap with the south bank built up
higher to take on high velocity flows
from large storm events.
