Abstract:

Sugden Reservior Dam is a 440-foot long 33-foot high earthfill dam. The spillway is a concrete ogee weir 127 feet long the outlet is a 36-inch diameter reinforced concrete pipe, and is controlled by a sluice gate. Generally the dam is in good condition. The following deficiencies were observed at the site lateral displacement and cracking at the joints between the spillway sidewalls and the approach channel sidewalls severe erosion approximately 2 to 3 feet in width along the north and south spillway sidewalls moderate erosion and the approach channel sidewalls severe erosion approximately 2 to 3 feet in width at the south abutment of the dam, and at the outlet headwall trees and vegetation on the downstream slope, trees and brush within the riprap on the upstream face trees and vegetation overhaning and growing on the floor of both the spillway and outlet discharge channels and slight leakage of the sluice gate. The test flood would not overtop the dam. Hydraulic analyses indicate that the spillway can discharge 7,042 cfs, or 137 percent of the test flood outflow with the pond at the low point on the top of the dam.
