Book excerpt: Based on a visual inspection, certain deficiencies were noted during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam and spillway. At the time of the inspection, the grass growing on the crest, and the upstream and downstream faces of the dam was on the order of 24 inches high. The grass should not be allowed to grow to a height that provides cover for burrowing animals or hinders inspection of the dam. Several areas of dense brush that may conceal animal burrows and trees exist on the crest and upstream and downstream faces of the dam. Several holes that appear to be animal burrows were observed in the upstream face, downstream face, and crest of the dam. The upstream face of the dam is grass covered throughout. A considerable amount of erosion of the upstream slope of the dam at the waterline has occurred. The concrete retaining wall located on the downstream side of th dam near the left abutment that serves to support the embankment at this location is cracked in several locations. The concrete slope paving located on the right bank of the principal spillway outlet channel at a point approximately 100 feet downstream of the spillway crest is undercut and the pavement subgrade and embankment extensively eroded.
