Located in Maricopa County, Arizona, the Guadalupe dam is a vital structure designed by the USDA NRCS to mitigate flood risk along the Salt River. Completed in 1975, this earth dam stands at a height of 27 feet and spans a length of 3152 feet, with a storage capacity of 523 acre-feet. The dam is regulated and inspected by the Arizona Department of Water Resources, ensuring its functionality and safety for the surrounding community.

With a spillway width of 200 feet and a high hazard potential, Guadalupe dam serves as a critical flood risk reduction infrastructure in the region. Despite its age, the dam is assessed to be in satisfactory condition as of December 2017, with regular inspections conducted to ensure its integrity. The dam's primary purpose is flood risk reduction, providing protection to the city of Guadalupe and the surrounding areas from potential inundation during heavy rainfall events.

Managed by the Natural Resources Conservation Service and nestled within the Los Angeles District, Guadalupe dam plays a crucial role in safeguarding the local community against flooding. With its strategic location and design, the dam continues to be a key asset in water resource and climate management efforts, highlighting the importance of infrastructure in addressing natural hazards and ensuring the resilience of communities in the face of changing environmental conditions.
