2.After Mining <br />Once mining has completed, the only loss will be an evaporative loss from the exposed water <br />surface which the gravel mining operation creates. <br />Annual evaporative depletion at mining completion from 109 acres of exposed water surface at <br />the Anderson Pit is calculated to be 340 acre-feet. Table 1 located in Appendix B shows <br />calculations of evaporative depletions from the Anderson Pit. <br />Total annual depletions from the gravel mining operations are estimated to be 340 acre-feet <br />during the post mining phase of the operation. <br />Credits <br />The Anderson Pit property possesses very senior water rights in the Bona Fide Ditch. The Bona <br />Fide Ditch has a flow of 65 cfs. The Anderson has 34 shares in the Bona Fide Ditch, which <br />results in 263 acre-feet of water per month between April 1 and November 15, while the ditch is <br />active. <br />The amount of water described above is more than adequate to augment the evaporative losses <br />upon completion of mining during the months which the Bona Fide Ditch is active since the <br />losses will be greater than during mining. Because of this, only a portion of those shares will be <br />converted. <br />Since the entire Anderson property will be dried up and irrigation will no longer take place on <br />the Anderson property, a portion of the water rights present will be converted to industrial use <br />during the mining phase and recreational and wildlife use upon completion of mining. <br />Anderson Pit February OS G-4 <br />
