Introduction
The San Miguel river watershed is located at the center of the state of Sonora, Mexico. For those familiar with the region, this watershed goes from Hermosillo to Magdalena parallel to the east of Mexico 15 freeway, its shape is elongated, the slope is in the south direction, water flows south freely, the basin in undammed. The outlet point is defined at the confluence of the San Miguel with the Zanjon river, beyond this intersection, both runoffs are stopped at the Abelardo L. Rodriguez dam, located at the periphery of the city of Hermosillo, the capital of the state.
The San Miguel is an intermittent river, long segments of dry sand bordered by riparian vegetation is its distinctive landscape, there are only a few places where water overflows onto the surface almost year-round.
The San Miguel river is a tributary of the Sonora river. Its basin has an area of 3,999.76 square kilometres, population was approximately 5,092 people in 2010, it could be considered a rural basin with a declining population.
Most of the land of the watershed, 95%, is classified as rangelands or forest, it is no surprise that cattle ranching is the main economic activity.
On the map below is delineated the San Miguel river watershed, the watershed encompasses land in 15 counties of Sonora, but just 4 have their local government within: Cucurpe, Opodepe, Rayon and San Miguel de Horcasitas, and at the lower part of the watershed, Hermosillo has important rural communities (towns), operatively there are 5 counties to deal with.
