The Deep Fork Watershed (HUC 11100303) covers an area of approximately 2,345 square miles in Oklahoma. The watershed is characterized by a mix of agricultural, urban, and forested land use. The hydrology of the area is influenced by the watershed's location in the southern Great Plains. The area experiences a humid subtropical climate with hot summers and mild winters. Snowpack is generally not a significant factor in the region's hydrology. Surface water in the Deep Fork Watershed is primarily supplied by the Deep Fork River, which flows through the center of the watershed. The river is used for recreation, water supply, and irrigation. The watershed also contains several reservoirs, including Lake Eufaula, Lake Okmulgee, and Lake Henryetta. These reservoirs are important sources of water for the region. Climate trends in the Deep Fork Watershed show increasing temperatures and more frequent extreme weather events, such as floods and droughts. These trends are likely to impact the region's hydrology and water availability in the future.
