Book Description
The dam built around 1852, has a total length of approximately 293 feet, consisting of a 113 foot long, broad-crested masonry spillway between two 90 foot long embankments with masonry downstream faces. The top of the embankments, at elevation 519.0, are approximately 14 feet wide and 3 feet above the spillway crest. The dam is 22 feet in height above the streambed of Furnace Brook and, with the pond level to the top of the dam, impounds approximately 105 acre-feet of water. At the right end of the dam is a canal leading to the Warren Corporation mill downstream. The inlet to the canal is a 6 foot wide by 5.5 foot deep masonry arch culvert. Based upon the visual inspection at the site and past performance, the project is, judged to be in fair condition. No evidence of instability of the project was observed. However, there are items which require maintenance and/or evaluation, such as deteriorated masonry at several locations on the dam and the absence of a low-level outlet for the dam. The spillway capacity, with the reservoir level to the top of the dam, is 1,900 cfs, which is equivalent to 16% of the routed test flood outflow.
