Abstract:

The dam is of irregular composition consisting of stone and earth embankments, two sluiceways, a spillway and several stone masonry wall sections. The dam has a hydraulic height of 11 feet and an overall length of approximately 120 feet. The spillway and sluiceways have a combined capacity of 230 cfs or 22 percent of the test flood outflow with flashboards and 345 cfs of 33 percent of the test flood outflow without flashboards. The dam is in generally good condition. However, it is rated as fair due to the inadequate spillway capacity, seepage through the stone masonry below the right sluiceway outlet pipe, and the voids beneath the cracked concrete floor of the spillway. It is recommended that the owner engage a qualified registered professional engineer to perform a detailed hydraulichydrologic investigation to determine overtopping potential and need for the total discharge capacity of the dam design a means to precent water from seeping through the masonry below the right sluiceway outlet pipe and investigate the voids beneath the spillway cap.
