Lions Bridge Dam Improvements

Project Description
Improvements to the dam for Mariners' Lake include the armoring of the entire downstream embankment, rehabilitation of the outfall culvert, and construction of a low level inlet structure to control the lake level and discharge from the lake. These improvements are necessary in order for the dam to receive certification of operation and maintenance from the State Department of Conservation and Recreation (DCR), Dam Safety Division.  The present spillway operation has stop-logs that are removed or replaced by Mariners' Museum staff using a crane machine to lift and place the logs. The dam has been overtopped by large storm events which have caused minor damage to the area that have been repaired.  In addition to these improvements, off-shore stabilization will be performed prior to removal of shoreline vegetation based on DCR's requirements.
