If the stated amount of water could be salvaged, it would, of course, have the effect of reducing the amount of imported supplemental water which must be brought into the Lower Basin of the Oolorado River System, if the economy of the affected area is to be preserved or expanded. . . . any water which might be salvaged, resulting from the lin- ing of the canals in Imperial and Ooachella Valleys, should first be available and employed to the end that these agencies of the State of California may continue in the future to firmly receive the supply of water to which the area is entitled, either by way of present perfected rights or contract rights, including the Pri- ority Agreement of 1931. When such obligation has been met if there remains any excess or surplus water resulting as salvaged water, then and in such event, such excess or surplus, if any, should be available for beneficial use in the area to support and vouchsafe the expanding and developing economy of the region.lO Both representatives of tbe Oolorado River Board and the agricul- tural agencies also testified that the amounts estimated to be salvaged, in their opinion, were overestimated.
