Mr. Rick Parsons, P.E. <br />L.G. Everist Combined Replacement Plan <br />be in acre-feet. <br />April 19, 2010 <br />Page 7 of 9 <br />In addition, the Applicant shall submit a report from the entity making replacements; for this plan, <br />that entity is the Varra Companies, Inc. ("VCI"). The report shall include an accounting of all of the <br />Rural Ditch water controlled by VCI, showing the total volume of water under its control and the <br />amount committed to each of the recipients of the water. <br />10. The Applicant shall perform an inspection and provide verification for all parcels of dried up land <br />used to generate augmentation credits during the term of this SWSP. The final verification of dry <br />up will be in the form of an affidavit signed by an individual having personal knowledge of the dry <br />up for the entire irrigation season for each parcel of land used in this SWSP. In accordance with <br />the attached protocol for dry-up of irrigated land, the Applicant shall provide a written notification <br />to the water commissioner and division engineer by May 1, 2010 and April 1, 2011 identifying the <br />lands to be dried up for the 2010 and 2011 irrigation season. By October 31, 2010 and October <br />31, 2011 the Applicant shall provide an affidavit to the water commissioner and division engineer <br />that identifies and confirms the lands that were dried up during the 2010 and 2011 irrigation <br />season in order that the final determination of augmentation credits for the irrigation season can <br />be made along with mapping showing any revisions to the dried-up acreage. The Applicant shall <br />modify accounting to reflect that the credit from any dried up fields containing alfalfa or native <br />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 less <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 />Depth to Ground <br />Water (Feet) Percent Reduction in CU Credit' <br /> Native Grass Alfalfa <br />1 85% 100% <br />2 50% 90% <br />3 30% 75% <br />4 20% 50% <br />5 15% 35% <br />6 10% 20% <br />7 5% 15% <br />8 0% 10% <br />1.
