I I I I I I I I I I I I I I I I I I I <:::;) c..'"") N ..:::. ,.... Q Mr, Don Higbee and Mr. David L. Pope November 12,1997 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 14, 15, and 16, replacements to senior surface water rights in Colorado replaced 20.0% of the stream depletions caused by pumping affecting those reaches. lIDs percentage reflects the fact that there was a call by a Colorado surface water right in those three reaches on 6 of the 30 days during September. 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. One delivery of water to the Offset Account was made during September, 1997. This delivery of water to the Offset Account from the HigWand Canal started at 0900 hours on 14 July, 1997 and continued through the month of September. This delivery was described in my letter to the Kansas Chief Engineer dated August 25, 1997. My letter dated October 9,1997 provided the summary of the deliveries from this source for the months of July, August, and September, 1997. The deliveries in September resulted in an addition of378.22 acre-feet of fully consumable water and 17.80 acre-feet of return flow water to the Offset Account. As of September 30,1997, 5207.08 acre-feet of water was being stored in the Offset Account, 3374.03 acre-feet of fully consumable water and 1833.05 acre feet of return flow water.
