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). | |
