The Big Sunflower Watershed (HUC 08030207) covers a land area of approximately 3,240 square miles in central Mississippi. The watershed is characterized by a humid subtropical climate, where precipitation is abundant throughout the year with a peak in the spring and fall. The watershed contains several small lakes and streams that contribute to the Big Sunflower River, which eventually flows into the Yazoo River. The watershed is also home to several reservoirs, including the Enid Lake and Grenada Lake, which are used for irrigation, recreation, and flood control purposes. Snowfall is rare in this area, but the watershed does experience occasional winter storms. The hydrology of the watershed is influenced by land use practices such as agriculture and forestry, which can impact water quality and quantity. Recent trends in the watershed include increased urbanization and changes in land use practices, which have put pressure on water resources and ecosystem health.
