The Pascagoula watershed (HUC 03170006) covers approximately 8,240 square miles in Mississippi and Alabama. The dominant hydrologic feature of the basin is the Pascagoula River, which flows 80 miles south and empties into the Gulf of Mexico. The basin receives an average of 65 inches of precipitation per year, with a peak snowpack of only a few inches, making it a mostly temperate climate. Surface waters in the basin are generally clear and are home to a variety of fish and aquatic life, including several endangered species. The basin is also home to several reservoirs, which are used for recreation, water supply, and hydroelectric power. The most interesting climatic trend in the Pascagoula watershed is the increase in extreme precipitation events in recent years, which can cause flooding and water quality problems. Overall, the Pascagoula watershed is an important resource for both the environment and the communities that rely on it.
