A week or two ago on this list, there were some questions/comments about the canals in the Yakima/Sunnyside area. I'm told that there are two books written on the subject, "Courage and Water," by Roscoe Sheller, and "They Knew our Valley," author unknown. Hope this is helpful. Searching for Bain/Bayne, Bennett, Bullock, Bussert, Evans, Helms, Hensley, Jones, Leinart, Loschen, Mason, Miller, Murry/Murray,Sadler/Saddler, Seiber, Shane, and Trauernicht.
