The Rio Yaqui is a significant river located in northwestern Mexico. It flows through the states of Sonora and Chihuahua, eventually emptying into the Gulf of California. The river is approximately 400 kilometers long and plays a crucial role in the region's agriculture by providing irrigation to surrounding farmland. The Yaqui people, an indigenous group, have historically lived along the river's banks. The river's ecosystem supports diverse wildlife and plant species, making it an important natural resource. Additionally, the Yaqui Valley is known for its fertile land, which benefits from the river's waters for crop cultivation.
