The corresponding decrease in stream <br /> <br />flow in the Conej os is a.n average annual flow of. 47.5 cubic feet <br /> <br />per second. This d<'i)crease. in stream flow. resulted in a large reduc- <br /> <br />tion irt pirect-flowdeliveries on the Conejos. <br /> <br />See Figure "7 from <br /> <br />COlorado Water ResQurces Circular No. 18, 1973, by .the U. S. Geo- <br /> <br />logical Survey, as. added to by D. H. McFadden, in appendix. This <br /> <br />addition indicates an average annual decline in diversions Of 60,000 <br /> <br />acre-feet. . For this report, the consumptive use portion of the <br /> <br />60,000 acre-feet is estimated at 20 percent. The average annual <br /> <br />depletion to the Conejos from the Compact study period (1928 to <br /> <br />1937) to the (1950 to 1967) period is then 34,400 plus 12;000, or <br /> <br />46,400 acre~feet. This compares favorably with the approximate <br /> <br />5.0,000 acre-feet illustrated by Figure 7 in Colorado Water Resources <br /> <br />Circular No. 18, 1973" by the U. S. Geological Survey. The 46,400 <br /> <br />acre-feet per year represents an average flow of 64 cubic feet per <br /> <br />second (cfs). <br /> <br />Seepage investigations reported. in the text and Table III of <br /> <br />the Tipton report show a change for the Conejos River from the gaging <br /> <br />station at Mogote to its mouth at Los Sauces from +27.4 cfs in <br /> <br />-6- <br />
