Is that <br /> correct? Based on total depletions equaling 34.66 acre-feet, then it appears <br /> you are proposing to wrap 5.82 acre-feet which is 16% of remaining depletions <br /> into the year 2022 which exceeds the SEO's guideline of 5% and exceeds the 6% <br /> that was discussed previously in the attached emails. Additionally, it appears <br /> that the depletions were distributed equally across all months in 2022 however <br /> it was suggested that the depletions be distributed according to the months in <br /> which the depletion occurred. Perhaps you could help me understand how <br /> these remaining depletions are wrapped into this approval period. <br /> I <br /> Correct, the remaining 5.82 acre-feet of depletions that occur after <br /> December 2022 were evenly distributed across 2022 since the on-going <br /> depletions accrue at a generally uniform (but decreasing) rate. This <br /> approach was proposed because the remaining depletions accrue at a <br /> miniscule rate of 0.05 ac-ft or less per month (for comparison, this equates <br /> to a flow rate of a third of a gpm or less...tiny in comparison to flows in St. <br /> Wain Creek and the South Platte River). The 6% value you referenced was <br /> calculated by the DWR as occurring in October 2023; this calculation was <br /> done when the initial plan was to do a multi-year SWSP approval spanning <br /> through October 2024. However, this proposal shifted to replacing all <br /> remaining depletions by the end of 2022 and that proposal was deemed <br /> acceptable in the e-mail correspondence I had with the DWR prior to me <br /> having my client execute the lease. <br /> 3. It appears that recharge accretions from the 12CW179 ponds accrue in Section <br /> 35, Township 5 North, Range 66 West according to paragraph 8.7. However <br /> this is -19 miles away from the pit where depletions occur. I am not sure if <br /> you have already discussed this with the division office/water commissioner to <br /> ensure that replacement water is provided above any calls. I am copying <br /> Michael Hein on this email. <br /> This accretion location is upstream of the Lower Latham Ditch, which is the <br /> first calling structure impacted by the Camenish Pit depletions. As such we <br /> believe this replacement source is adequate for the calling regime. <br /> Thank you, <br /> Wenli Dickinson, P.E. <br /> Water Resource Engineer <br /> I <br /> P 303.866.3581 x8206 <br /> 1313 Sherman St, Suite 821, Denver, CO 80203 <br /> wenU.dickinson@state.co.us I dwr.colorado.gov <br /> https://mail.google.com/mai I/b/ALGkdOxhJsspQ9 WQy6M8ZvEdoQU rzvydSw2AkGT9zE9ZwUt2J rQJ/u/O/?i k=96aa8a08c9&view=pt&search=al I&permt... 7/8 <br />
