Abstract:

The dam is comprised of a 705 foot long, 49 foot high, earth fill embankment, and a 31 foot wide stone spillway. The spillway has a capacity of 195 and 380 cfs with and without flashboards, which is 27 and 57 percent of the 12 PMF outflow, respectively. The remaining outflow overtops the spillway training walls and adjacent Ashby West Road. The top of the dam, elevation 889, is not overtopped. This dam is in generally fair condition. It is recommended that the owner engage a registered professional engineer to investigate downstream seepage conditions, to further evaluate the adequacy of the spillway, and to recommend a method of removing and properly backfilling trees stumps on the downstream face of the dam. Furthermore, the owner should institute certain remedial measures including permanent removal of spillway flashboards repair of erosion at the upstream slopes near the gatehouse repair of gatehouse masonry backfilling of animal holes maintenance of proper growth on the downstream slopes removal of small trees, brush and debris within the spillway channel monitoring of differential settlement within the floor of the spillway channel and periodic testing of all intake and outlet gates to insure they are in working order.
