Watershed and course
The Maurice River, pronounced "Morris," is approximately 50 mi (80 km) long with a drainage area of 386 sq mi (1,000 km2). It is the second longest and second largest tributary to Delaware Bay. Its watershed includes an extensive southern portion of the coastal forested wetlands known as the Pine Barrens. Its mouth on Delaware Bay is surrounded by extensive salt marshes and has provided an historically important oystering ground.
It is born at the confluence of Still Run and Scotland Run, beneath the waters of Willow Grove Lake in Pittsgrove, Salem County and flows generally south-southeast, passing 2 miles (3 km) west of Vineland. At Millville it is impounded to form the Union Lake reservoir, approximately 3 miles (5 km) long. South of Millville it becomes navigable, forming a 10-mile (16 km) estuary that empties into Maurice River Cove on Delaware Bay. The estuary is joined from the northeast by Menantico Creek, the Manumuskin River, and Muskee Creek.
Water quality and stewardship
The river is considered especially pristine for the region, forming a critical ecological link between the Pine Barrens and the Delaware Bay systems. It is the location of one of the only stands of wild rice in New Jersey, and provides habitat for 53 percent of the species in New Jersey designated as endangered. In 1993, Congress designated 28.9 miles (46.5 km) of the river and its tributaries as the Maurice National Scenic and Recreational River, as part of the National Wild and Scenic Rivers program.
A local nonprofit organization, Citizens United to Protect the Maurice River and Its Tributaries, Inc., is a regional watershed organization that focuses its work on the Maurice River watershed, from Willow Grove Lake southward. The South Jersey Land and Water Trust focuses on the northern portion of the watershed, from Willow Grove Lake northward.
