Flowing through the arid Arizona-Sonora borderlands, the San Pedro River is a vital lifeline. This "damned miracle" is one of the Southwest's last undammed rivers, supporting over 80 mammal species—including jaguars and pumas—along with amphibians, imperiled yellow-billed cuckoos, 250+ migratory bird species, and unique native fish. Its incredible biodiversity demands protection.

However, the San Pedro is drying up. Unsustainable groundwater pumping by a growing population has caused base flows to decline by 67% since the 1940s, creating a significant annual water deficit. This crisis stems from unchecked population growth and a lack of effective water-conservation planning.

The San Pedro River, the Southwest's largest undammed river, flows north from Mexico into Arizona. It provides vital habitat for dozens of endangered species and millions of migratory birds.

The San Pedro River, the Southwest's largest undammed river, flows north from Mexico into Arizona. It provides vital habitat for dozens of endangered species and millions of migratory birds. However, a proposed 28,000-home development threatens to deplete its waters, endangering countless wildlife.

To showcase the San Pedro's beauty and vulnerability, the Center has teamed up with filmmaker Dina Kagan to create a powerful 13-minute film.

The Trump administration waived 41 environmental and public-health laws.

These waivers allowed for the construction of a border wall through the San Pedro River, the last free-flowing, undammed river in the American Southwest.

The proposed border wall poses a significant threat to the San Pedro River, a vital ecosystem.
