<br />(0 " 0" 0 1 '! <br /> <br />same system. Successive use of water implies that the sllllle water is put to <br /> <br />another usli following a previous use with or without treatment in the same <br />, <br /> <br />or another 'system. Successive uses generally occur as water moves through <br /> <br />the basin s~stem. In the South Platte River basin, the most common form of <br />successive use is that of municipal wastewater being used for agricultural <br /> <br />irrigation ~d irrigation return flows again being rediverted or pumped for <br /> <br />another irrllgation application. In downstream basin communities, the gro!U1d' <br /> <br />water aquif~r is recharged from surface irrigation and may again be used as <br /> <br />a domestic ~OIIIIIIunity ground water supply source, discharged, and the process <br /> <br />repeated . <br /> <br />Fig. 3 is a bar graph of the hydrologic inventory for the average annual <br /> <br />water suppli( in the South Platte River basin. Only 17 percent of 304,000 <br />. 6 <br />acre-feet (375 x 10 x m3) of the total annual surface water supply that is <br /> <br />available fdlr consumptive use leaves the basin. The maJority of this water <br /> <br />leaves duri4g high spring discharges. As mentioned earlier, if the Narrows <br /> <br />reservoir is constructed on the South Platte River above Fort Morgan, this <br />quantity could possibly be reduced to the South Platte River compact level of 0 <br />50,000 acre.,feet (62 x 106 x m3) annual discharge to Nebraska. Approximately: <br /> <br />70 percent of the basin supply is consumptively used for agricultural irriga- , <br />tion while DlUnicipal and industrial consumptive use is 8 percent of the total.! <br /> <br />It is appare~t from these figures that the water supply of the basin is <br /> <br />intensively used. The issue-in the basin is not one of putting surplus basin <br />waters to use. The issue is which uses are the basin waters going to be put <br />to and the efficiency of those uses. The term efficiency of use is directly <br />related to the productivity per unit of water consumptively used for a <br /> <br />partiCular activity. <br /> <br />;, <br /> <br />: <br />';1 <br /> <br /> <br /> <br /> <br /> <br />15 <br />
