<br />*The subbasin tunoff is the Colorado River flow at Cameo less the Colorado
<br />River & Roaring Fork River Flow at Glenwood Springs.
<br /> During ,the 18 year study period, the water consumed within the
<br /> basin is estimated to have averaged 85,800 acre feet per year.
<br />
<br />Figures on watershed rlUloff, stream depletion and the undepleted
<br />
<br />water yield of the subbasin are given in the following table.

<br />The irrigated land of the subbasin as measured by
<br />the Bureau of Reclamation in 1939 totaled 52,470 acres. The
<br />results of re-study of the land in 1951 also by the Bureau of
<br />Reclamation show that irrigation had been expanded to a total
<br />of 55,944 acres of land. A recent check on irrigated land in-
<br />dicatesthat the presently irrigated land is about 57,480 acres.
