The table also shows the resulting stream depletion for each <br /> <br />division. <br /> <br /> TABLE XXIX <br /> Present Irrigation Potential Irrigation <br /> Area Depletion Area Depletion <br />Division Acres Acre Feet Acres Aore Feet <br /> ----:r:J <br /> i '" . 7,400 4,000 4,200 <br />Upper San Juan 7,060 <br />Navajo-Blanco 6,120 6,400 3,550 3,700 <br />Piedra u.,700 4,900 3,000 3,100 <br />Pine 37,880 49,200 5,000 6,500 <br />Florida g;h30 16,300 5,740 12,900 <br />Animas-LaP1ata 27,120 30,300 45,920 82,700 <br />l1ancos n,ooo 15,400 1,000 1,400 <br />l'loElmo 41,000 71,800 35,450 62,700 <br />Total 150,310 202,200 103,660 177 ,200 <br />Reservoir Evaporation and Hunicipa1 Use <br />Consumptive use of water by reservoir evaporation and by the munici- <br /> <br />palities of the basin is small compared with irrigation.
