Pope <br />September 15, 1997 <br /> <br />Page 2 <br /> <br />river reaches where no replacements or only partial replacements were made to replace out-of~ <br />priority depletions to senior surface water rights in Colorado. <br /> <br />Table 3 shows the remaining stream depletions caused by irrigation pumping in excess of the <br />pre-Compact entitlements which were not replaced by making replacements to senior surface <br />water rights in Colorado. These stream depletions were computed using the wellhead depletions <br />shown in Table 2 with the Ground Water Accounting Model. Please note that in Re.aches 14, 15, <br />and 16, replacements to senior surface water rights in Colorado replaced 35.5% of the stream <br />depletions caused by pumping affecting those reaches. This percentage reflects the fact that there <br />was a call by a Colorado surface water right in those three reaches on 11 of the 31 days during <br />July. The remaining depletions shown in Table 3 are the estimated stream depletions caused by <br />irrigation pumping in excess of the pre-Compact entitlements remaining after replacements were <br />made to senior surface water rights in Colorado. Table 3 also shows the estimated depletions to <br />usable Stateline flew, which were calculated using the assumptions in paragraph 5.B of the <br />Resolution, and the replacements to Stateline flows which were made during the month. <br /> <br />A delivery of water to the Offset Account was started at 0900 hours on 14 July, 1997. This <br />delivery was described in my letter to the Kansas Chief Engineer dated August 25, 1997 and <br />involves a daily delivery of a variable quantity of water obtained from shares of the Highland <br />Canal owned by LA WMA. A daily accounting spreadsheet showing the daily operations of this <br />activity has been designed and is currently being completed to summarize the deliveries for July. <br />As of August 1, 1997, 136.35 acre-feet of water was being stored in the Offset Account, 13L53 <br />acre-feet of consumable water and 4.82 acre feet of Colorado in-state return flow water. <br /> <br />Please contact me if you have any questions or require additional information. <br /> <br />Sincerely, <br /> <br />A /. / <br />/f L j it/l~ <br /> <br />.,-., <br /> <br />Steven J.
