VIDEO: Mystic River FNP Dredging

Mystic River Federal Navigation Project in Groton and Stonington, Conn., is being performed by Cashman Dredging and Marine Contracting Company, LLC, of Quincy, Mass.

The Mystic River FNP consists of: a 15-foot channel, 125 feet from the Sound up to the railroad bridge, then 100 feet wide up to highway bridge (U.S. Route 1); a 12-foot channel above the highway bridge to the upper wharves at the Seaport Museum; a 9-foot by 8.5-acre anchorage in the harbor north of Mason Island; and a 9-foot turning basin above the railroad bridge.

Cashman began work on the project in November last year and it will take about five months to complete the works.

A mechanical dredge using various types of clamshell buckets will remove approximately 250,000 cubic yards of material from the Mystic River Federal navigation project, restoring the channels and anchorage area to their authorized depths.
