Sonora River

Río 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.

Watershed

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 watershed is subdivided into six smaller watersheds.

Ecology

Biotic communities found within the watershed in order of importance by the area covered are the Sinaloan thornscrub, the plains of Sonora subdivision, semidesert grasslands, the Madrean evergreen woodland, and the central gulf coast subdivision. Average annual precipitation is 375 millimetres (14.8 in) which occurs in two seasons, late summer-early fall and winter-early spring.

Physician naturalist Edgar Alexander Mearns' 1907 report of beaver (Castor canadensis) on the Sonora River may be the southernmost extent of the range of this North American aquatic mammal.

Sonora

Sonora (Spanish pronunciation: [soˈnoɾa]), officially Free and Sovereign State of Sonora (Spanish: Estado Libre y Soberano de Sonora), is one of 31 states that, with the Federal District, comprise the 32 federal entities of Mexico. It is divided into 72 municipalities; the capital city is Hermosillo. Sonora is located in Northwest Mexico, bordered by the states of Chihuahua to the east, Baja California to the northwest and Sinaloa to the south. To the north, it shares the U.S.–Mexico border with the states of Arizona and New Mexico, and on the west has a significant share of the coastline of the Gulf of California.

Sonora's natural geography is divided into three parts: the Sierra Madre Occidental in the east of the state; plains and rolling hills in the center; and the coast on the Gulf of California. It is primarily arid or semiarid deserts and grasslands, with only the highest elevations having sufficient rainfall to support other types of vegetation.

Sonora is home to eight indigenous peoples, including the Mayo, the Yaqui, and Seri. It has been economically important for its agriculture, livestock (especially beef), and mining since the colonial period, and for its status as a border state since the Mexican–American War. With the Gadsden Purchase, Sonora lost more than a quarter of its territory. From the 20th century to the present, industry, tourism, and agribusiness have dominated the economy, attracting migration from other parts of Mexico.
