The headwaters of the Mianus River lie in the southeastern corner of New York State, from whence the river flows about 20 miles in a southerly direction and empties into Captain Harbor through Cos Cob Harbor. Vessel traffic on the river is from its mouth to a dam at the Village of Mianus (immediately north of U.S. Route 1), a distance of 1.8 miles. Maintenance dredging is proposed for the Mianus River project to restore it to its authorized dimensions. Based on hydrographic survey data, this will involve the removal of about 25,000 cubic yards of material to attain the six foot channel depth. A clamshell or bucket dredge will be used to dig the material and place it in dump scows. These dump scows will be towed to an open water site for disposal of the material. Since the project site is heavily used by recreation boaters, there will be no dredging during the peak boating season. Dredging operations will commence in the spring of 1978 and is expected to be completed before the boating season in May 1978.
