TOTAL RIVER DISCHARGE
Maximum discharge along the river is currently at the reporting a streamflow rate of cfs. This is also the highest stage along the Cohansey River, with a gauge stage of ft at this location. This river is monitored from 1 different streamgauging stations along the Cohansey River, the highest being situated at an altitude of ft, the .
The Cohansey River is a 30-mile long river in southern New Jersey that flows through Cumberland County before emptying into the Delaware Bay. The river has a rich history, having played a vital role in the development of the area's agricultural and industrial sectors. The river is fed by several tributaries, including the Manantico Creek and the Maurice River. There are several reservoirs and dams along the river, including the Dividing Creek Dam and the Maskell's Mill Dam. These dams are used for flood control and to provide water for agricultural irrigation. The Cohansey River is also popular for recreational activities such as fishing, boating, and birdwatching. The river is home to a variety of fish species, including striped bass, bluefish, and white perch. The river is also surrounded by farmland, with crops such as corn, soybeans, and wheat being grown in the area.

History of the River
The Cohansey River (also called Cohansey Creek) is a 30.6-mile-long (49.2 km) river in southern New Jersey in the United States. The river drains approximately 108 square miles (280 km2) of rural agricultural and forested lowlands on the north shore of Delaware Bay.
It rises in central Salem County, approximately 5 miles (8 km) southeast of Woodstown, and flows south, through rural Cumberland County. It interconnects with Sunset Lake, which is in turn fed from Mary Elmer Lake, both of which are located in Bridgeton's park system. At Bridgeton it becomes navigable, although very shallow at low tide: 1 foot to a few inches coming through downtown Bridgeton. The city boat ramp downtown is unusable during low tide due to about 20 feet (6 m) of mud between the channel and the ramp. The river widens into a tidal estuary, approximately 10 miles (16 km) long, that flows south, then west, entering Cohansey Cove on Delaware Bay, approximately 7 miles (11 km) southwest of Bridgeton. The mouth of the estuary is surrounded by extensive wetlands and salt marshes.
In colonial times the river provided an anchorage for vessels approaching Philadelphia. In 1774, the small port village of Greenwich on the river near its mouth was the scene of an incident similar to the more famous Boston Tea Party in which imported tea was burned as a protest against taxation. The river was also known as the Cesaria River in colonial times.
Navigation and Coast Pilot
The Cohansey River is in Region 3 of the US Coast Guard and NOAA Mapping system. The following information is reproduced from the US government coast pilot information. This is from the 39th edition and may be out of data, so please do not use this for navigation: Cohansey River, which empties into the northeast side of Delaware Bay 31 miles northwestward of Cape May Light, is used mostly by pleasure craft, although some petroleum is transported to Bridgeton. Cohansey Light (39°20'30"N., 75°21'41"W.), 42 feet above the water, is shown from a black skeleton tower with a white daymark on the south side near the natural entrance. A dredged cut through the narrow neck of land on which
the light stands gives a more direct approach to the river; the cut, 0.3 mile northwest of Cohansey Light, is marked on its west side by lights at the inner and outer ends. The river is unmarked above the dredged cut. In April 1990, the controlling depths were 5 feet to Fairton; thence in 1990-September 2003, shoaling to less than 1 foot to Bridgeton. The usual approach to Cohansey River is along the
axis of the dredged cut, but the natural channel eastward of Cohansey Light is sometimes used; the latter has a controlling depth of about 7 feet, and unmarked shoals with depths of 4 to 6 feet must be avoided on either side. Local knowledge is advised when using this approach and in the dredged channel in the upper part of the river off Bridgeton.
