The Upper Arkansas Watershed covers an area of approximately 13,900 square miles and includes parts of Colorado, Kansas, and Oklahoma. The watershed is primarily fed by snowpack in the Rocky Mountains and is home to several popular ski resorts. The hydrology of the watershed is dominated by the Arkansas River, which flows through Colorado, Kansas, and Oklahoma and provides irrigation water for agricultural operations in the region. Surface water in the watershed is heavily used for both recreation and agriculture, with several major reservoirs, including the Pueblo Reservoir, serving as important water sources. The watershed also contains several unique habitats, including wetlands and riparian areas that provide important habitat for fish and wildlife. In recent years, the Upper Arkansas Watershed has experienced several extreme weather events, including droughts, floods, and wildfires. These events have highlighted the importance of water management and planning in the region and have led to increased efforts to protect and conserve the watershed's natural resources.
