River Summary: The Santa Cruz River is a 184-mile-long river that flows through the southern part of Arizona and northern part of Mexico. The river has a rich history, with evidence of human activity along its banks dating back over 4,000 years. The hydrology of the river has been significantly impacted by human activity, including diversion of water for agricultural use and the construction of dams and reservoirs. The two main reservoirs on the river are Lake Patagonia and the Rio Rico Reservoir. The river is also an important source of water for irrigation, supporting agriculture in the region. In recent years, efforts have been made to restore the river and its ecosystem, including the removal of invasive plant species and the reintroduction of native fish species. The river also provides recreational opportunities, including fishing and boating.
