The Obion Watershed (HUC 08010202) covers approximately 3,320 square miles across northwest Tennessee and southeast Missouri. It is home to several large rivers, including the Obion River, that provide critical water resources for agriculture, industry, and recreation. The watershed has a humid subtropical climate, with hot summers and mild winters. It receives an average of 53 inches of precipitation annually, with most falling as rain. Snowfall is relatively rare in the region. The Obion Watershed is an important source of surface water for both human and ecological needs. It contains several large reservoirs, including Reelfoot Lake, which is a popular destination for fishing, boating, and birdwatching. The watershed is also home to many unique aquatic species, including several threatened and endangered species. In recent years, the Obion Watershed has experienced significant changes due to land use practices and climate change. Increased agricultural activity has led to higher levels of soil erosion and nutrient runoff, which can negatively impact water quality. Climate change has also led to more frequent and severe floods and droughts in the region. These changes highlight the importance of sustainable land management practices and the need for effective water management strategies in the Obion Watershed.
