National Dam Inspection Program. Converse Lake Dam (CT 00044). Connecticut Coastal Basin, Greenwich, Connecticut. Phase I Inspection Report.
Abstract
The dam, built in the early 1900's, is a stone masonry gravity section with an earth fill and a dry-laid stone retaining wall on the downstream slope. There is a series of dikes located approximately 200 feet northwest of the dam. The dam is 175 feet long (not including the spillway) and 8 feet wide at the top, which is at elevation 426.7 and 30 feet above the streambed of Converse Pond Brook. The spillway is 30 feet long and cut into bedrock at the right end of the dam. The outlets are 16 inch (O.D.) and 21 inch (I.D.) cast iron pipes located at the central part of the dam. Based upon the visual inspection at the site and past performance, the dam is judged to be in poor condition. The general condition of the masonry appears to be fair, although there are trees and brush on the downstream slope and the dry laid stone retaining wall at the toe of the dam needs repair. There are areas which require monitoring and maintenance such as seepage through the dam and dikes, the growth on the downstream slope, the stone wall at the toe of the dam and brush in the spillway. The spillway capacity at the test flood is 360 cfs with the remaining 330 cfs outflow being released over the dikes. The spillway capacity with the lake level to the top of dam is 520 cfs.
