The Buckingham Reservoir Dam is an earth embankment 400 feet in length and 30 feet in maximum height. The spillway is 50 feet long, constructed of concrete. As a result of the visual inspection and the review of limited available data regarding this project, the dam, spillway and dike appear to be in poor condition. The vertical and horizontal alignment of the dam is good. The downstream slope has several trees and high brush, especially at the abutments. Erosion gullies up to 8 inches deep on the downstream slope, due to vehicular traffic, were noted. The riprap on the upstream slope is in good condition with a few unprotected areas. Considerable seepage as evidenced by wet area downstream from the toe of dam and at the toe of the natural slope at the left abutment was noted. Several springs were observed, although these springs did not appear to carry fine material. The concrete spillway and dike are in fair condition. The concrete spillway had areas of erosion, spalling and deterioration. Seepage was noted at the base of the left training wall. The dike was overgrown with brush however, no seepage was observed. Apparent settlement or slumping was observed at upstream edge of dikes crest immediately to the right of the spillway. Apparent movement has occurred at the downstream toe adjacent to the left spillway training wall. The vertical and horizontal alignment was good. A few minor erosion gullies were noted on the downstream slope. The capacity of the spillway is adequate to pass the 100-year test flood outflow of 1,260 CFS without overtopping the dam and dike.
