Show X-48 UPDATING THE HOOVER DAM DOCUMENTS 2 Ltr. to: Mr. Erwin N. Griswold, Subj: Present Perfected Rights all instances, the Federal establishments listed in Article II(D) are located so that nearly all the diverted water not consumptively used returns to the river at locations where it is available for consumptive use in the United States or for satisfying the Mexican Treaty obligation. There is some time lag on return flows and the sources are sometimes difficult to identify. Nevertheless, the concept of a dual limitation can be administered reasonably well for the Federal establishments along the mainstream. In attempting to reach agreement among the parties in Arizona v. California on a stipulation of present perfected rights under Article VI of the Decree, it was emphasized by them that the major irrigation claimants occupy distinctly different hydro-logical positions as related to return flows to the Colorado River. Except for Palo Verde Irrigation District, any measurements of return flows would be highly inaccurate and impracticable in terms of expressing consumptive use as defined in the Decree. In brief, the various districts' hydrological positions are as follows: Palo Verde Irrigation District - is immediately adjacent to the Colorado River and essentially all of its diversions not consumed in plant growth or lost by evaporation return eventually to the Colorado River or contribute to stabilization of ground waters. As the ground water is now fairly stable, there is little ground-water movement to the river. From a practical standpoint nearly all of the district's return flow can be measured as surface flows in drains. Valley Division, Yuma Project - is immediately adjacent to the Colorado River and essentially all of its diversions not consumed in plant development or lost by evaporation return to the Colorado River. However, those return flows are intermixed with return flows from the Yuma Mesa Irrigation and Drainage District and from the Yuma Auxiliary Project. Some return flow is to the river above Mexico's point of diversion at Morelos Dam. Other return flow reaches the river in the limitrophe section. Still other return flow is delivered to Mexico at the boundary pumping plant under informal arrangements not covered by the treaty with Mexico or by contract between Mexico and the Yuma County Water Users' Association. |
