Yarmouth’s long-awaited dredging project is complete, said Town Manager Nat Tupper.

The Army Corps is expected to do its final inspection of the work in the spring, after enough ice melts.

The dredge crew removed about 103,000 cubic yards of material from the Royal River navigation channel, returning the narrow, twisting waterway to a state unseen in more than a dozen years.

The $2.5 million federal dredge project was paid for by the Army Corps of Engineers, and was long overdue. The three marinas on the Royal River hired their own dredgers, who removed an additional 40,000 cubic yards of silt and mud from mooring areas.

Harbors and waterways are supposed to be dredged every 10 years, but Yarmouth, like many communities, waited longer because of federal budget shortfalls and the recession.
