<br />14. DISCt1SSION OF UIIT'IMATE DEPIETIONS.
<br />
<br />Ultimate depletion in Colorado, as shown in the foregoing table, is
<br />estimated at 3,821,000 acre feet annually. Previous estimates of this office
<br />(see Statement of July 20, 1944) placed the possibilities of present and future
<br />depletions in Colorado at 4,600rooO acre feet. Principal difference between
<br />the two figures is in the estimates of future exportations. Potential export
<br />diversions are estimated in the Report at 1,267,000 acre feet annually, whereas
