Rick Parsons <br />M &G SWSP <br />May 6, 2014 <br />Page 4 of 7 <br />share per year. The surface water, or tailwater, runoff averaged 18.7 acre -feet per year and the <br />deep percolation runoff averaged 37.5 acre -feet per year. The total return flows represent <br />approximately 39% of the historical farm headgate delivery, or 1.12 acre -feet per share. The <br />monthly HCU factors as a percentage of lateral deliveries and the winter time return flows as a <br />percentage of irrigation season's consumptive use credits are as shown in the table below: <br />Polly Mann Fulton Ditch Shares Factors <br />In 2013, the water attributable to the 61 Fulton Ditch shares was delivered into the pit <br />during the irrigation season. Starting again in 2014 some of the water attributable to the 61 Fulton <br />Ditch shares will be delivered into the pit during the irrigation season. The water delivered to the pit <br />will be multiplied by the CU factors above to determine the CU portion and the surface return <br />portion. The CU portion will be lagged to the river and credited as replacement for lagged <br />evaporation depletions and the calculated wintertime return flow obligations. The surface return <br />portion will exit the northwest corner of the pit through a corrugated metal pipe under 120th Ave and <br />will reach the east bank of the South Platte River on the north side of 120th Avenue. Winter time <br />return flows will be calculated based on the total amount recharged during the previous irrigation <br />season. In the previous SWSP we indicated that the recharge operation will require a <br />measurement structure capable of measuring and recording the farm headgate deliveries into the <br />pit, and a measurement structure capable of measuring and recording the surface return portion <br />that is returned to the river. The surface return measurement structure must not also intercept <br />storm water runoff. No credit will be given to water delivered to the pit or returned back to the river <br />that is not measured to the satisfaction of the water commissioner. According to the information <br />received from the Applicant, on April 2, 2014 the required water measurement device was installed <br />thus the measurement structure is capable of measuring and recording the surface return portion <br />that is returned to the river. However the water commissioner has to also approve this structure <br />before credit can be given to water delivered to the pit or returned back to the river. <br />Non - irrigation uses are limited in agreement with other Fulton Ditch historic consumptive <br />use analyses, current ditch operations, and expected yields during a dry year. It is possible the <br />ditch will be limited to its 1865 right of 79.7 cfs during parts of the season. This would result in <br />deliveries to each of the three ditch sections for 2 days on and 4 days off with 1 cfs delivered to <br />each 38.4 shares owned (1 miner's inch per share) for about 10 days per month. This translates to <br />approximately 1.59 cfs for all 61 shares. <br />Long Term Augmentation Requirements <br />In accordance with the letter dated April 30, 2010 (attached) from the Colorado Division of <br />Reclamation, Mining, and Safety ( "DRMS "), all sand and gravel mining operators must comply with <br />the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for <br />protection of water resources. The April 30, 2010 letter from DRMS required that you provide <br />information to DRMS to demonstrate you can replace long term injurious stream depletions that <br />result from mining related exposure of ground water. <br />The reclamation plan filed with DRMS was to create two ground water lakes. This <br />reclamation plan required the Applicant to file and obtain a water court approved Plan for <br />Jan <br />Feb <br />Mar <br />Apr <br />May <br />Jun <br />Jul <br />Aug <br />Sep <br />Oct <br />Nov <br />Dec <br />CU as % of <br />Diversion <br />- <br />- <br />- <br />55.9 <br />69.7 <br />71.5 <br />71.6 <br />67.5 <br />59.8 <br />41.5 <br />- <br />- <br />Replacement as <br />% of Summer CU <br />0.6 <br />0.5 <br />0.4 <br />- <br />- <br />- <br />- <br />- <br />- <br />- <br />1.1 <br />0.8 <br />In 2013, the water attributable to the 61 Fulton Ditch shares was delivered into the pit <br />during the irrigation season.
