The Gila Gravity Main Canal diverts approximately 700,000 acre-feet annually from the Colorado River at Imperial Dam. The canal serves five irrigation and drainage districts, as well as a number of other contractors and domestic areas. It is federally owned and its administrative board is made up of representatives from each irrigation district. The canal currently faces three problems: sedimentation, imprecise flow measurement, and a lack of real-time monitoring capabilities. Planned responses to these problems include dredging, the installation of a Replogle flume, remote monitoring and canal automation systems, and the application of a clay sealant. This project will be funded by a grant from the Border Environment Cooperation Commission (BECC) and a challenge grant through the US Bureau of Reclamation.


Presented during the Third international conference on irrigation and drainage held March 30 - April 2, 2005 in San Diego, California. The theme of the conference was "Water district management and governance."
