Of course subsequent to suthorization, we <br />do model and model studies, hydrology studies. to size the dams and <br />reservoirs to an optimum size to get the most beneficial use out of it. <br />Consequently to that. substantiating document had a total acting <br />capacity of something like 767,000 a.c. in all of our reservoirs. We have <br />now built those reservoirs and we only have a total capacity of 516,000 a.f. <br />So OUf total storage is actually 251,000 a.f. less than what was in the <br />substantiating report. The joint use pool come about in cooperation with <br />the Corps of Engineers - we needed to move some of OUf water down <br />from the upstream reservoirs during the winter months so that we could <br />make room for our imported water from the Colorado River Basin during <br />the spring. So it became obvious that we could use some additional <br />capacity in Pueblo Reservoir during the winter. And the Corps, in their <br />studies determined that the major flood threat - Pueblo is from the <br />summer thunderstorms - so we were able to reduce required flood <br />control in the winter to about 27,000 aJ. of space, and in the summer it is <br />required to be 93.000 aJ. of space. So with that type of oper~t.ion we were <br />able to make 66,000 a.f. of space available for joint lIses for other <br />purposes. And the Bureau - we don't necessarily say that the winter <br />W[lter would push that in there or whether it would he a project water or <br />whatever type of water it was, it is just conservation space that we can <br />use during that time. And this year is the first time that we did go to store <br />water into that space and, as Tommy reported, about 18,000 a.f. The City <br />of Pueblo I believe sold 4,000 a.f. to Ft. Lyon Canal. so we were only <br />required to release about 13,000 to 14,000 a.f. to evacuate that water by <br />April 15, and that is essentially how the joint use pool came about. <br />Mr. Pope: You indicated that the primary reason originally for <br />creating the joint use pool was discussions between the Bureau and the <br />Corps in order to be able to move water from the upstream reservoirs <br />down to Pueblo to make room for Colorado River water or transmountain <br />water. <br />Mr. Gibbens: That is correct. <br />Mr. Pope: And then at what point, he alluded to it, at what point was it <br />determined that space could also be used for any types of storage that we <br />need to use it for. And winter water in storage is just one of the purposes <br />of the project that was also included in the substantiating report. <br />winter storage water. <br />Mr. Pope: But the concept of a jOint use pool per se was not included in <br />the substantiating report. <br />Mr. Gibbens: No. not exactiy. <br />Mr. Pope: Well, is __. <br />Mr. Gibbens: Well let me go further, some of this spill that we have <br />made is the result of - like I was saying earlier - to make use of the <br />upstream reservoir for inflow from the Colorado River Basin. We <br />presentiy, we've spilled 43,000 a.f. of water to date from Pueblo and that's <br />made 66.000 aJ. available in our upstream reservoir for Colorado River <br />imports. Our present forecast is for an additional 40,000 or a 107,000 a.f. <br />from the Colorado River. If we actually get that much water but there is <br />going to have to be a demand between now and about the middle of <br /> <br />*Blank spaces indicate that the tape recording was not <br />understandable. <br /> <br />63 <br />
