National Program for Inspection of Non-Federal Dams. Lynn Reservoir Dam (MA 01285), Massachusetts/Rhode Island Coastal Basin, Lynn, Massachusetts. Phase 1 Inspection Report.

摘要

The Lynn Reservoir Dam, owned and operated by the City of Lynn, is an earthen embankment structure located in the central portion of Lynn, Massachusetts. The dam has a hydraulic height of 10 feet and is 1,920 feet long. The top width is 18 feet. As a result of the visual inspection and the review of available data, the Lynn Reservoir Dam is considered to be in poor condition. Major concerns are: deterioration of the concrete foundation of the outlet works building, badly corroded and perforated structural members of the outlet works control bridge; deterioration of the outlet works abutments, and apparent erosion on the downstream slope of the dam. The test flood pool would rise to within 0.6 feet of the embankment crest.
