Pueblo Dam is a large concrete dam located on the Arkansas River in Pueblo, Colorado. Completed in 1975, it serves multiple purposes, including flood control, water supply, and recreation. The dam creates the Pueblo Reservoir, which is a popular spot for fishing, boating, and picnicking. The dam is operated by the U.S. Bureau of Reclamation and plays a crucial role in managing water resources in the region. It helps to regulate river flow and provides water for agricultural and municipal use, benefiting both local communities and ecosystems along the Arkansas River.
