<br />65. The to(,a] irriglltion water supply to' be' made' avai]able by th.;
<br />project would consist of imported water, conserved flood 'f1ows, private
<br />supplies reregulated in project reservoirs, and l~sflble return flows.
<br />Rercgulated priYitte sllpplies include some winter Bows of the
<br />Arknnsas River that are presenUy diverted' for direct-flow use but
<br />which by agreement, could be con vcrted to more beneficial summer'
<br />use. U;rough storage in the Pueblo Reservoir, Ret,urn flows of the
<br />project munieiplll water are est,imllted at 70 percent. The total
<br />irrig-Iltjon helldg-Ilte supply is estimated at .50 percent more than tbe
<br />initial supply, bl\scd upon successive reuses of the water at tbe rate
<br />of 40 percent return flow from each appliclltion, The next table sbows
<br />tbe souvce of wllter to be made availab]e for the Arkansas Valley,
