5. All recharge ponds must have a staff gauge installed such that the gauge <br /> registers the lowest water level in the pond. The staff gauge must be readable <br /> from a readily accessible location adjacent to the pond. <br /> 6. All recharge areas must be maintained in such a way as to minimize <br /> consumptive use of the water by vegetation. No recharge area may be used for <br /> the planting of crops during the same irrigation year that it is used as a <br /> recharge site without prior approval from the water commissioner or <br /> division engineer. <br /> 7. The amount of water recharged to the alluvial aquifer is determined by measuring <br /> the amount of water delivered to the recharge structure and subtracting: <br /> a. the amount of water discharged from the recharge structure, <br /> b. the amount of water lost to evaporation (see item 8, below), <br /> c. the amount of water lost to consumptive use due to vegetation located <br /> within the recharge structure, and <br /> d. the amount of water retained in the recharge cture t has not yet <br /> percolated into the ground. <br /> 8. Net evaporative losses from the recharge stru e t b tracted from the <br /> volume of water delivered to the pond. Eva r sse ust be taken every <br /> day the pond has a visible water level. If th pon a of have a stage-surface <br /> area curve approved by the water com .ss r th aximum surface area of <br /> the pond must be used to determine the losses. Monthly loss factors <br /> prorated for the number of days h visible water level may be used <br /> as may real time evaporation d from A or a local weather station. If the <br /> pond is not inspected on a r ti basis t ough the month, no prorating of <br /> monthly factors will be all owe <br /> 9. The amount of accre " m e recharge structure will be credited only in <br /> accordance with cree of augmentation or substitute water supply plan <br /> approved by the ate gineer. <br /> 10. All water de" d ec ge must be fully consumable: <br /> a. c ge ery rights or the CU portion of changed senior ditch rights; <br /> b. tran sin water that has been imported into the South Platte River basin; <br /> c. nontrib ry water; <br /> d. excess (unused) accretions from the previous recharge of fully <br /> consumable water; <br /> e. water diverted in priority after"notice" of intent to fully consume the water; <br /> f. water diverted under free river. <br /> 11. Water may be delivered to recharge only if the net impact of the associated plan <br /> for augmentation is not negative. Water must first be delivered or exchanged to <br /> offset negative impacts of the plan for augmentation before it may be diverted for <br /> recharge. <br /> 12. Accounting must be performed on a daily basis with reports submitted at least <br /> monthly and within 30 days of the end of the month for which the accounting is <br /> being made. The volume of water diverted into recharge must be provided to the <br /> water commissioner weekly when requested by the water commissioner. <br /> Administration Protocol - Recharge <br /> Revised February 1, 2008 <br />
