Pohick Creek forms in the vicinity of Burke and flows southeast past the western edge of Fort Belvoir to empty into the tidal Pohick Bay, which itself empties, along with Accotink Bay, into Gunston Cove, an embayment of the tidal Potomac River. Pohick Creek is a popular stream for whitewater kayaking, rafting, and paddling, providing Class II and III rapids along a 5.5-mile (8.9 km) stretch between Hooes Road (Virginia Secondary Route 636) and the Richmond Highway (U.S. Route 1) at Lorton.

Several tributaries of the Pohick Creek are impounded by dams constructed under the Watershed Protection and Flood Prevention Act to prevent soil erosion and flooding. Originally eight dams were planned, but from 1970 to 1985, only six were actually built.


Variant names


The following variant names have been listed on the Geographic Names Information System by the United States Geological Survey.


Course


Pohick Creek forms at the confluence of Rabbit Branch and Sideburn Branch in Burke, Virginia. Pohick Creek Creek then flows southeast, forming the border between Burke and West Springfield. After crossing the Fairfax County Parkway, it enters Newington and descends into a gorge where the Gerry Connolly Cross County Trail follows the creek, crossing it eight times. It then passes into Lorton and crosses Interstate 95, the CSX RF&P Subdivision, and U.S. Route 1. It then meets the Potomac River in Pohick Bay about 0.5 miles north of Springfield Farms.[2]


Watershed


Pohick Creek drains 32.21 square miles (83.4 km2) of area, receives about 43.5 in/year of precipitation, has a topographic wetness index of 409.88 and is about 31.0% forested.[4]
