Parker Street Dam is an earthfill dam with a paved roadway along the crest. The original embankment has been filled in on the downstream side to form a parking area for those swimming at the lake. There is a timber box spillway located approximately in the center of the dam. The overall condition of the dam is good. There are no signs of distress or instability in the dam. The hazard potential is rated as high. Parker Street Dam is considered inadequate in view of its lack of spillway capacity to pass the SDF 12 PMF without overtopping the dam. The spillway is capable of passing a flood equal to 8 percent of the PMF 16 percent of the 12 PMF, and is assessed as inadequate. At present, the engineering data available is not sufficient to make a definitive statement on the stability of the dam, but based on the findings of the visual inspection, the preliminary assessment of static stability is that it is satisfactory. Actions are recommended along with a timetable for their completion.
