The Lower Pearl Mississippi watershed covers an area of approximately 7,500 square miles, spanning parts of Mississippi and Louisiana. The Pearl River is the main hydrological feature of the watershed, and it flows into the Gulf of Mexico. The area experiences a humid subtropical climate with high temperatures and rainfall throughout the year. Snowfall is rare, but when it does occur, it is typically light and melts quickly. The watershed includes several reservoirs, including the Ross Barnett Reservoir and the Okatibbee Reservoir, which are used for water supply, recreation, and flood control. The water quality of the watershed is affected by agricultural runoff, municipal wastewater discharges, and industrial activities. Climate change is likely to exacerbate the risks of droughts and floods in the area, causing further challenges for water management and environmental conservation efforts.
