Pope and Ms. Mary Louise Clay January 7, 1999 Page 2 river reaches where no replacements or only partial replacements were made to replace out-of- priority depletions to senior surface water rights in Colorado. Table 3 shows the remaining stream depletions caused by irrigation pumping in excess of the pre-Compact entitlements which were not replaced by making replacements to senior surface water rights in Colorado. These stream depletions were computed using the wellhead depletions shown in Table 2 with the Ground Water Accounting Model. Please note that in Reaches II, 12, and 13, replacements to senior surface water rights in Colorado replaced 0% of the stream depletions caused by pumping affecting those reaches. Also note that in Reaches 14, 15, and 16, replacements to senior surface water rights in Colorado replaced 0% of the stream depletions caused by pumping affecting those reaches. These percentages reflect the fact that there was a call by a Colorado surface water right in those reaches on none of the days during November. The remaining depletions shown in Table 3 are the estimated stream depletions caused by irrigation pumping in excess of the pre-Compact entitlements remaining after replacements were made to senior surface water rights in Colorado. Table 3 also shows the estimated depletions to usable Stateline flow which were calculated using the assumptions in paragraph 5.B of the Resolution, and the replacements to Stateline flows which were made during the month. As indicated in Table 3, 585.6 acre-feet of fully consumable water has been made available to Kansas under the provisions of paragraph 58 of the Resolution. Under those provisions, 585.6 acre-feet will be moved from the Colorado Consumable Water subaccount to the Kansas Consumable Water subaccount of the Offset Account 30 days ilfter the date of this notification letter in order that evaporation be charged as provided for by paragraph 5B of the Resolution. As of November 30, 1998, there were 5116.87 acre-feet being stored in the offset account. Please contact me if you have any questions or require additional information. Sincerely, AJIJ~ Steven J.
