The Pearl River is a major river system in the southeastern United States. The river flows for 485 miles through Mississippi and Louisiana, emptying into the Gulf of Mexico. The river has a rich history, playing a significant role in the Civil War and serving as a transportation route for Native American tribes.

The hydrology of the Pearl River is heavily influenced by several large reservoirs and dams, including the Ross Barnett Reservoir and the Bonnet Carré Spillway. These structures help manage flood control, water supply, and hydroelectric power generation.

Recreational activities along the Pearl River include fishing, boating, and camping. The river also supports agricultural activities, with farms and ranches along its banks producing crops such as cotton, soybeans, and rice. Despite its importance, the Pearl River faces threats from pollution and habitat destruction, highlighting the need for continued conservation efforts.
