A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Chopawamsic Creek is a 6.8-mile-long (10.9 km) [1] tributary of the Potomac River in Prince William and Stafford counties, Virginia. Chopawamsic Creek is formed by the confluence of the North and South Branches of Chopawamsic Creek and empties into the Potomac River south of Quantico at the Marine Corps Base Quantico's Air Station. Breckenridge Reservoir lies at the stream's confluence with the North and South Branches. Along with its North Branch, Chopawamsic Creek forms part of the boundary between Prince William and Stafford counties. The North Branch flows through part of the Chopawamsic Backcountry Area in Prince William Forest Park. [2]
A tributary or affluent is a stream or river that flows into a larger stream or main stem river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean.
The Potomac River is located within the Mid-Atlantic region of the United States and flows from the Potomac Highlands into the Chesapeake Bay. The river is approximately 405 miles (652 km) long, with a drainage area of about 14,700 square miles (38,000 km2). In terms of area, this makes the Potomac River the fourth largest river along the Atlantic coast of the United States and the 21st largest in the United States.

The Board on Geographic Names decided upon Chopawamsic Creek as the stream's official name in 1891. Previously, it had been known by the following names according to the Geographic Names Information System:
The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
