White's Mill Pond dam which was built before 1923 is a
340-foot long earthfill dam with upstream and downstream
dry stone masonry walls. The dam has a maximum height of
13 feet and consists of a spillway, low level outlet, an
intake toi a plant, and an earth dike. The following
deficiencies were observed at the site: severe seepage at
several locations along the toe of the dam; downstream
stone masonry walls are out of plumb; lack of access to
the low level outlet operator; erosion at the low point
of the dam crest; bulging of the downstream masonry wall
in several locations; stone missing from the upstream
face of the spillway, mortar missing from the stone
masonry spillway of the dam; heavy growth of brush and
trees on the dam crest and on the dike; and an
accumulation of debris in the discharge channel.
Hydraulic analyses indicate that the spillway (without
stoplogs) can discharge 520 cfs, or 76 percent of the
test flood outflow before the dam is overtopped. (With
the stoplogs, the spillway can discharge 170 cfs or 22
percent of the test flood outflow before the dam is
overtopped).
