National Program for Inspection of Non-Federal Dams. Brierly Pond Dam (MA 00143), Blackstone River Basin, Millbury, Massachusetts. Phase I Inspection Report.

Abstract

The following visible signs of distress were noted at the site: erosion and insufficient riprap on the upstream face of the dam; the lack of permanently-installed equipment for opening the gate at the low-level intake; leakage around the closed gate; seepage in the tailrace downstream of the dam; and overgrowth of vegetation on the dam, the dike, and over the outlet channel. An outflow test flood of 2,560 cfs (derived from one-half the probable maximum flood) will overtop the dam by about 2.4 feet. The outlet even when fully opened is inadequate as a spillway because it can discharge only 7 percent of the test flood.
