<br />:!":I <br />C:) <br />~ <br />....-1 <br /> <br />Potential Water Requirements <br /> <br />Principal water-development project possibilities in the subbasin are the <br />proposed Bostwick Park and Dallas Creek projects of the Bureau of Reclama- <br />tion. Both are currently being investigated by the Bureau of Reclamation <br />and would provide adequate water supplies for most of the suitable new la~ds <br />in the subbasin, and for most of the presently cultivated lands which now <br />have insufficient water supplies. Total water supplies available for pro- <br />ject development are adequate to fully meet project requirements. Estimates <br />of potential water requirements reflect the approximately 15,755 additional <br />acres that would be irrigated, and have been adjusted for acreages of <br />presently cultivated lands that will be inundated by project reservoirs. <br /> <br />Estimates of potential water requirements or water-supply depletions in the <br />subbasin are summarized in table 33. <br /> <br />Table 33.- Potential water requirement, Uncompahgre Subbasin 11 <br /> <br />Net crop consumptive use 11 <br /> <br />189,614 acre-feet <br /> <br />Riparian vegetation, nonbeneficial <br />phreatophytes, seeped lands and <br />incidental areas <br /> <br />87,365 acre-feet <br /> <br />Municipal, domestic and livestock use, <br />reservoir evaporation and <br />foreseeable recreation development <br /> <br />10,930 acre-feet <br /> <br />Total potential requirement <br /> <br />287,909 acre-feet <br /> <br />II Exclusive of industrial requirements. <br />II 121,055 acres including potential project development. <br /> <br />Opportunities for Developments Through Watershed Protection <br />and Flood Prevention and Other USDA Authorities <br /> <br />Possible p. L. 566 Projects <br /> <br />In appraising the opportunities for water and related land resource develop- <br />ments in the Uncompahgre subbasin, it appears that most of the major <br />water storage opportunities will be developed in connection with the proposed <br />Bostwick Park and Dallas Creek projects of the Bureau of Reclamation. <br />Several possible P. L. 566 watershed protection and flood prevention projects, <br />however, appear to have merit and could be developed if group-type action <br />were taken by the local people. These projects are largely of a flood pre- <br />vention nature and are listed in table 34. Cost and benefit ratios have not <br />been computed for these prospective projects; however, it appears that they <br />do present opportunities for project-type action. Other potential P.
