National Program for Inspection of Non-Federal Dams. Cobble Mountain Reservoir Dam (MA 00068), Connecticut River Basin, Russell, Massachusetts. Phase I Inspection Report.

Abstract

The dam is a sluiced earth fill between massive rock toe embankments. The top of dam is about 730 feet long about 250 above the valley bottom at the toe. The dam is generally in GOOD condition, well maintained, with no excessive or dangerous leakage. The preliminary hydrologic and hydraulic analysis for this LARGE size, HIGH hazard dam indicated that the spillway is adequate. The test field is the PMF and for the tributary drainage area of 45.8 square miles of mountainous terrain which is more than 80% forested, the unit discharge rate is 1440 CFS/square miles. (Author)
