Dredging News

Posted 7/28/2015

The U.S. Army Corps of Engineers, New England District is proposing maintenance dredging of the Mianus River Federal Navigation Project in Greenwich, Conn.

The project consists of a 6-foot channel, 100 feet wide, running from Cos Cob Harbor up the Mianus River to a point about 400 feet downstream of the Boston Post Road Bridge, then, 75 feet wide to the bridge.

The proposed work consists of the maintenance dredging of about 60,000 cubic yards of primarily fine-grain clay and silt in order to return the Federal project to its authorized dimensions.

“The upper portion of the channel has shoaled into depths as shallow as – 4 feet Mean Lower Low Water across the entire width of the channel,” said Project Manager Jack Karalius, of the Corps’ New England District, Programs and Project Management Division in Concord, Mass. “The shoals are hindering navigational access and compromising vessel safety.”

The work will be performed by a private contractor, using a mechanical dredge and scows, under contract to the government. The dredge will remove the material from the bottom of the river and place it in scows which will be towed by tug to the Western Long Island Sound Disposal Site, about 6 miles away, where the material will be released.

Dredging is anticipated to take approximately 2 – 4 months between Oct. 1 and Jan. 31 of the year or years in which funding becomes available.

The town of Greenwich has requested maintenance dredging of the Federal navigation project. The river and harbor are used predominantly by recreational boats, and also several commercial fishing boats.

The last time the Mianus River was maintained was in 1985 when approximately 53,000 cubic yards of sediment was dredged and placed at the Western Long Island Disposal Site.

Press Release, September 22, 2014

Authorities in Chiang Mai Province have inspected the banks of the Ping River to talk with trespassers and have them move out before the start of river dredging to alleviate flooding problems along the river.

The board will take about three months to observe the flow and characteristics of the river and talk with people who dwell informally along the Ping River before beginning to carry out dredging of up to 90 meters in width and 20 kilometers in distance in order to create a deeper water way to prevent flooding in Chiang Mai.

Invaders who have occupied the river banks are being asked to move out; non compliant offenders will be legally prosecuted.
