The pumped water wO'uld be discharged directly intO' the <br />canal and diversiO'ns at the headwO'rks wO'uld then be reduced a <br />prO'pO'rtiO'nate amO'unt, A narrO'w strip alO'ng the canal between PilO't <br />KnO'b lind DrO'p 4- wO'uld prO'vide a sO'urce with a salinity ranging frO'm <br />700 to' \900 milligrams per liter, <br /> <br />Butler ,Valley Well Field <br />This plan prO'pO'ses to' cO'nstruct a field O'f 15 wells in Butler <br />Valley, lqcated sO'utheast O'f Parker, ArizO'na, to' withdraw: 46,000 <br />acre-feet O'f grO'und wat!!r per year, The quality O'f the water is in <br />the range O'f 400 milligrams per liter, The Granite Reef Aqueduct, an <br />existin$' feature O'f the Central ArizO'na PrO'ject, wO'uld serve as the <br />dischadge pO'int fO'r the pumped water, and diversiO'ns to the <br />Aqued1.lct frO'm the CO'IO'radO' River wO'uld be reduced a like amO'unt, <br /> <br />prO'tective and ,Re&'1llatO'ry Pumping Unit <br />T*e PrO'tective and RegulatO'ry Pumping Unit, located O'n, the <br />sO'uthWllst ArizO'na bO'rder, is an authO'rized and partially cO'nstructed <br />feature' O'f the CO'IO'radO' River Basin Salinity CO'ntrO'l Act, the same <br />Act wbichauthO'rized this, study, The unit will ultimately consist O'f <br />up to' ",5 wells (21 have been cO'nstructed to' date) which are being "- <br />installed O'ver a periO'd O'f time to' make up the declining flO'w in the <br />Yuma Valley agricultural drains, which have histO'rically made up part <br />O'f th~Mexican Treaty water deliveries.
