National Program for Inspection of Non-Federal Dams. Pleasant Street Dam (MA 00838), Merrimack River Basin, Dracut, Massachusetts. Phase 1 Inspection Report
Pleasant Street Dam consists of an approximately 93 ft. long stone masonry spillway with a brick building at each abutment. The spillway itself is approximately 15 ft. high and probably founded on bedrock. There is a 4 ft. square low-level gated outlet through the spillway structure and stoplogged conduit outlets through the building at the right abutment. The overall condition of Pleasant Street Dam can only be considered fair, primarily because the spillway of the dam was obscured by heavily flowing water and the operation of the low-level outlet was not demonstrated. However, visible portions of the dam are generally in good condition, and the dam is performing adequately. There was no evidence of settlement, lateral movement or other signs of structural failure, or other conditions which would warrant urgent remedial action. With the water level 3.8 ft. above the spillway crest, corresponding to the estimated top of dam level, the spillway capacity is approximately 2,500 cfs, which is 12 percent of the test flood outflow.
