The Raw Water Pond was designed and constructed as an earthfill structure with clay core and cutoff along the centerline. The embankment is 1190 feet long, with a toe to crest height of 25.2 feet and a crest width of 25 feet. The Raw Water Pond outlet works is a 14 inch diameter steel pipe with an intake at the bottom of the Pond. The outlet works maintains the operating pool approximately 1.5 feet below the invert of the principal (and emergency) spillway. A gate valve and flow monitoring weir box are located downstream of the embankment. Outlet works flows are discharged to the Treated Water Pond below. Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Raw Water Pond is considered to be poor. This assessment is based primarily on visual observations that indicate a possible inadequate margin of safety against slope failure of the embankment. Spillway capacity is 'inadequate' because the non-overtopping flood discharge was found, by using the HEC-1 computer program, to be in 0.18 PMF.
