Pope and Ms. Mary Louise Clay <br />June 12, 1998 <br /> <br />Page 2 <br /> <br />~ <br />Q') <br />(.0 <br />~ <br /> <br />Compact entitlements for those river reaches where no replacements or only partial replacements <br />were made to replace out-of-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 all reaches <br />below John Martin Reservoir replacements to senior surface water rights in Colorado replaced <br />0% of the stream depletions caused by pumping affecting those reaches. This percentage reflects <br />the fact that there was no call by a Colorado surface water right in those reaches on any of the 30 <br />days during April. The remaining depletions shown in Table 3 are the estimated stream <br />depletions caused by irrigation pumping in excess of the pre-Compact entitlements remaining <br />after replacements were made to senior surface water rights in Colorado. Table 3 also shows the <br />estimated depletions to usable Stateline flow which were calculated using the assumptions in <br />paragraph 5.B, of the Resolution. Since the measured Stateline flow during April, 1998 was <br />59584 acre-feet, 9.9% of the estimated depletions in each reach was replaced in the reach where <br />the depletions occurred. At the end of April, 1998, the remaining credit from the previous <br />releases of consumable water from the Offset Account was the 159.2 acre-feet reported after the <br />replacement operations conducted for November, 1997. <br /> <br />As of April 30, 1998, no water was being stored in the Offset Accountsince the entire contents <br />of the account was spilled from January 14 through January 17, 1998. The 500 acre-feet to be <br />used for the storage charge was being stored in Meredith Reservoir for delivery to the Offset <br />Account on a date to be determined under the provisions of the letter attached at Enclosure 1. <br /> <br />Please contact me if you have any questions or require additional information. <br /> <br />Sincerely, <br /> <br />/~JU~~ <br /> <br />Steven J.
