Historical development:

The Irrigation District 041 Rio Yaqui was created by Presidential Decree in 1951. The use of surface runoff in the upper basin in the Bavispe river tributary of the Yaqui river was built La Angostura dam with a storage capacity of 920 Hm3, in the middle basin of the Yaki river the Elias Calles dam was built with storage capacity of 3020 Hm3, and in the lower basin the dam Álvaro Obregón was built with storage capacity of 3227 Hm3. Within the limits of the Irrigation District there are 350 deep wells.


The larger conveyance network of water supply, dams and main canals are operated by technical personnel of the National Water Commission and they deliver the irrigation water to 42 irrigation modules in which the District is divided. Users of each module are arranged to form Civil Partnerships Users Yaqui River, its technicians are responsible for distributing the volume of water to the users registered in the census; annually the total volume of water is delivered to each module in block and is measured in a strategic control point of the larger network. Within Modernization Programs District recently installed a communication wireless network that allows automation of wells that can operate efficiently.

 

The Irrigation District 038 Rio Mayo created by Presidential Decree in 1956. The use of the surface runoff in the Mayo River was built Adolfo Ruiz Cortinez dam, with a capacity of 1115 Hm3, and in the area of the Irrigation District has 130 deep wells. The district is divided into 16 irrigation modules and its operation is very similar to that used in the Irrigation District 041. Users of the irrigation districts and officials of the National Water Commission aware of improving water use efficiency to achieve better productivity manage financial resources to the State Government and Federal Government to improve the irrigation infrastructure of the smaller conveyance network.
