Depth to Ground <br />Water (Feet) <br />Percent Reduction in CU Credit' <br />Native Grass <br />Alfalfa <br />1 <br />85% <br />100% <br />2 <br />50% <br />90% <br />3 <br />30% <br />75% <br />4 <br />20% <br />50% <br />5 <br />15% <br />35% <br />6 <br />10% <br />20% <br />7 <br />5% <br />15% <br />8 <br />0% <br />10% <br />Mr. Rick Parsons, P.E. <br />L.G. Everist Combined SWSP <br />Page7of9 <br />MOUNTAIN MEADOWS, South Park, Colorado, March 1, 1990; Revised September 1, 1991 <br />February 3, 2012 <br />and 2013. By October 31 of 2012 and 2013 the Applicant shall provide an affidavit to the water <br />commissioner and division engineer that identifies and confirms the lands that were dried up <br />during the 2012 and 2013 irrigation season in order that the final determination of augmentation <br />credits for the irrigation season can be made along with mapping showing any revisions to the <br />dried -up acreage. The Applicant shall modify accounting to reflect that the credit from any dried <br />up fields containing alfalfa or native grass was assessed in the following manner: <br />(a) For fields deep tilled or chemically treated to successfully kill alfalfa or native grass, 100% <br />credit will be given for consumptive use as otherwise computed under the conditions of this <br />approval. <br />(b) For fields not deep tilled or chemically treated to successfully kill alfalfa, records of monthly <br />monitoring of depth to groundwater at existing irrigation wells or existing or new monitoring <br />wells or piezometers within % -mile of each alfalfa or native grass field must be maintained. <br />Credits will be reduced according to the following table when depth to groundwater is Tess <br />than the depth assumed to provide no significant contribution to alfalfa growth. <br />Measurements taken at the start of each month will determine the necessary reduction in <br />credit to be applied during the following month. The applicant may use another <br />methodology upon review and approval by the State Engineer and Division Engineer. <br />1. Adapted from EVAPOTRANSPIRATION AND AGRONOMIC RESPONSES IN FORMERLY IRRIGATE <br />13. This substitute water supply plan may be revoked or modified at any time should it be determined <br />that injury to other vested water rights has or will occur as a result of this plan. Should this supply <br />plan expire without renewal or be revoked prior to adjudication of a permanent plan for <br />augmentation, all use of ground water must cease immediately. <br />14. If reclamation of the mines at the gravel pit sites included in this SWSP produce a permanent <br />water surface exposing groundwater to evaporation, an application for a plan for augmentation <br />must be filed with the Division 1 Water Court at least three years prior to the completion of mining <br />to include, but not be limited to, long -term evaporation losses. If a lined pond results after <br />reclamation, replacement of lagged depletions shall continue until there is no longer an effect on <br />stream flow. <br />15. Dewatering at the Lohmann Pit, Rinn Valley Pit, and Lupton Meadows Pit will produce delayed <br />depletions to the stream system. As long as the pits are continuously dewatered, the water <br />returned to the stream system should be adequate to offset the depletions. However, once <br />dewatering at the sites cease, the delayed depletions must be addressed. A plan that specifies <br />how the post pumping dewatering depletions (including refilling of the pit) will be replaced, in time, <br />
