The Army Corps of Engineers has agreed to dredge Oswego Harbor.
U.S. Sen. Charles Schumer says the long-overdue project is expected to get underway in June and take about one month to complete.
Army officials say more than 72,000 cubic yards of sediment must be dredged from the harbor every three to four years, but the
Lake Ontario port hasn't had its sediment dredged since 2008.
The project will be paid for with $786,000 approved by Congress for the recovery from Hurricane Sandy, which caused storm damage at the port.
The dredging and improvements already underway to improve rail access to the port are expected to increase capacity by almost 50 percent.
Oswego is the only deep water port on the U.S. shores of Lake Ontario.
