POltions of the water system serving <br />District camps were operated until the end of 1939, but dismantling <br />for sale or removal to salvage of the unused lines, tauks, and equip- <br />ment was begun in June of that year. The construction power <br />system was first energized in March 1933 and continued to deliver <br />power until January 15, 1940 when the last section in use, serving <br />San Jacinto tunnel, was deenergized. The telephone system main <br />lines have been retained for the permanent communication system to <br />provide necessary service for aqueduct operation and maintenance. <br />The Banning exchange has been closed, a switchboard opened at <br />Hayfield, and all unnecessary tap lines dismantled. District roads <br />have been transferred to Riverside and San Bernardino counties, <br />excepting patrol roads, branch roads to Hayfield, Eagle Mountain, <br />and Iron Mountain camps and the main and branch roads in the <br />Colorado River area north of Earp, California. <br /> <br />Const,uction Wnter System <br />WjtbJhe e-"ceJlti~n Qf a SI!!l!.lI_a!11_o,!nt Q( \~'it~r used bY.one_con- <br />tractor in completing Hayfield pumping plant construction, all <br />water produced and delivered since June 30, 1938 was for use of <br />District forces installing pumping plant equipment, testing and <br />conditioning aqueduct features, and maintaining moisture in cov- <br />ered conduits and tunnels. Service was necessarily maintained in <br />those pOltions of the system which supplied Gene, Iron Mountain, <br />Eagle Mountain, and Hayfield camps until Colorado River water <br />was flowing through the aqueduct and each plant was equipped to <br />make use thereof. Delivery of water through the construction <br />system ended in December 1939, after nearly seven years of service <br />during which 198,166,742 cubic feet of water, equivalent to 4,549 <br />acre feet, were delivered for construction purposes and domestic <br />use, between Morongo Canyon camp in the Coachella Valley and <br /> <br />[13 ] <br />
