National Program for Inspection of Non-Federal Dams. Whigville Reservoir Dam (CT 00379), Farmington River Basin, Burlington, Connecticut. Phase I Inspection Report.
Abstract
Whigville Reservoir Dam is an earthen embankment structure with a concrete/boulder core wall. The dam is 460 feet long and has a maximum height of 54 feet. The 40 foot long concrete/boulder spillway is located at the right side of the dam. Slope paving forms the approach to the spillway. The downstream face is mortared stone masonry. Stone masonry training walls form the wasteway section. The outlet works consist of an upper and lower gatehouse each of which connect to submerged concrete intake structures. A 24 inch diameter blow off pipe passes under the wasteway channel to a stone masonry waste pot. The dam is judged to be in generally poor condition. The riprap on the upstream face is in generally good condition. The vertical and horizontal alignment is good. The downstream slope is covered with an extensive growth of trees and brush. Apparent seepage and wet areas were noted near the toe and at both sides of the spillway channel. The concrete parapet walls are in fair condition, with areas of erosion, spalling and deterioration noted. The concrete spillway weir is in poor condition with severely deteriorated concrete. The spillway is not adequate to pass the PMF spillway test flood outflow (7730 CFS) without overtopping the dam. The test flood would overtop the dam by about 4.2 feet. The spillway would pass about 20 percent of the test flood outflow without overtopping the dam.
