Ross Barnett Reservoir, Reservoir in Rankin County, United States.

Ross Barnett Reservoir is a reservoir in Rankin County, Mississippi, formed by a dam on the Pearl River that creates a large body of water with numerous coves and wooded shores. The lake stretches across several counties and includes both open water areas and narrower river channels upstream from the main dam.

The dam was built in the 1960s to prevent flooding along the Pearl River and to supply drinking water for the growing capital region. Since then, the reservoir has served both water supply needs and recreational purposes for surrounding communities.

The name honors a former governor, and today families spend weekends here fishing or boating on the calm water. The shoreline offers picnic spots under trees where groups gather for cookouts, especially during warmer months.

Several access points allow entry to different sections of the lake, with some areas better suited for small boats than others. Most activity happens from spring through fall when the weather is milder and water levels remain stable.

During certain winter months, special fishing rules protect fish populations by limiting hook sizes and quantities. These measures help balance recreation with conservation and ensure healthy fish stocks for future seasons.
