Ro Sonora (Sonora River) is a 402-kilometer-long river of Mexico. It lies on the Pacific slope of the Mexican state of Sonora and it runs into the Gulf of California. The Sonora River watershed covers 10,040 square miles (26,000 km 2) of public land.

What is the Sonora River? The Sonora River is subdivided into six smaller watersheds.

The Sonora River watershed covers 10,040 square miles (26,000 km2) of public land. Slopes range from steep orientations in the upper part of the watershed to more gradual topographies in the valleys.

The Sonora River is located in the state of Sonora in northwestern Mexico. It rises south of Cananea, near the US border, and flows south and then southwest through the western flanks of the Sierra Madre Occidental.

As we explore the geography, ecology, and cultural significance of the Sonora River, we uncover a story of adaptation, survival, and the enduring connection between people and nature in the arid north.

For 17 miles the river forms the international boundary between the U.S. state of Arizona and Mexico. The river drains a vast arid and semiarid sector of the North American continent, and because of its intensive development it is often referred to as the Lifeline of the Southwest.
