o 00 l'- - 4 - lands lie only a few feet above the level of the river; this will make drainage difficult. Water Requirements. --Water requirements at the farm were estimated at 2.97 acre feet per acre for all project lands in the vicinity of Baggs and upstream and at 3.52 acre feet for the Two Bar area. These estimates made allowance for the effect of precipitation as well as for farm-ditch losses and losses in application on the 6/ farm. - Table 1 IRRIGATION WATER REQUIREMENTS PER ACRE AT THE FARMS Acre-feet per acre Major project Two Bar area area.

C.: 1962) Total water requirements at the reservoir sites are estimated at 127,100 acre feet. This requirement would make allowance for conveyance losses in canals. The major loss would occur in the 58-mile-long Pothook Canal, with a conveyance loss of approximately 29.5 percent of the diversion. Water losses are estimated at only about 9 percent of the diversion for the 7/ area. - Dolan r,lesa Canal, and at about 35 percent of the diversion for the Two Bar 6/ Ibid. P. 13 V Ibid. P. 14
