Other Aurora wells that may deliver <br />water into an individual demand (such as a golf course) have not been included in Table 8 as <br />they serve relatively small demands that have been excluded from the typically comprise small <br />amounts of water supply and have not been included in Table 8. <br />The largest ground water supply is derived from the Cherry Creek alluvial wellfield, which wells <br />pumped an annual average of approximately 3,700 ac-ft during 2000-2004. However, as the <br />priorities associated with the alluvial wellfield have relatively junior water right priorities <br />compared with downstream water rights, much of the pumping from the Cherry Creek alluvial <br />wellfield requires augmentation (replacement). No record of historic pumping from the Cherry <br />Creek non-tributary wells was found. The Senac Wells averaged about 200 ac-ft per year (total <br />for all wells) during the 2000-2004 period. The Griswold and Quincy wells were not operational <br />unti12005. Suggested treatment of Aurora's ground water systems in SPDSS modeling is <br />discussed in the Operational Information section. <br />City of Aurora Operating Memorandum 17 of 29 <br />
