View of experimental section about 5 miles west of Woodland. Experiments being conducted to determine effect of salt treatment of canal banks and bottom on seepage loss on canals. 1000' section of this canal was divided into 10, 100' ponds by means of 11 water-tight bulk heads. This view shows "upper" pond No. 1 during first trial to determine rate of loss of water before treatments were started. Note that water level has dropped about a foot in depth from upper limit as noted from line of wet soil on bank 710-F-2 1940 October 28
