Show APPENDIX X X-49 3 Ltr. to: Mr. Erwin N. Griswold, Subj: Present Perfected Rights Finally, some return flow from diverted waters crosses the international boundary to Mexico in the ground-water aquifer. This quantity will vary depending on the amount of ground-water pumping in the United States and in Mexico. Yuma Auxiliary Project - diversions from Imperial Dam are routed through the Gila Gravity Main Canal and the main conveyance system of the Yuma Mesa Irrigation and Drainage District before reaching Yuma Auxiliary Project main canal and lands. Operational losses are apportioned among some five irrigation districts which use all or a part of these facilities. After delivery to farms, water not otherwise consumed percolates into a ground-water mound under the Yuma Mesa. Part of this mound flows eastward into permanent storage; part flows southward in the ground-water aquifer across the international boundary into Mexico; part is pumped and reused by private landowners on the Yuma Mesa; and part flows westward, along with unidentified Yuma Mesa Irrigation and Drainage District ground waters into the Yuma Valley where it is further intermixed with Valley Division return flow before being picked up by pumps or open drains; additionally, some flows northward to the South Gila Valley. There is a great time lag before return flow reaches the river, and it is not possible to accurately separate this district's return flow from that of other districts. Imperial Irrigation District - the only return flow to the Colorado River is seepage from the approximately 14-mile section of the All-American Canal between Imperial Dam and Pilot Knob Wasteway. All other return flow is to the Salton Sink and not to the Colorado River. From a Decree standpoint, "consumptive use" as defined in Article I (A) is essentially equal to diversions. Reservation Division, Yuma Project, California (Non-Indian portion - return flow from non-Indian lands is so intermixed with return flow from the All-American Canal that it is difficult to identify accurately the source. |
