APPLICATION FOR UNDERGROUND WATER RIGHTS, CHANGE OF WATER RIGHTS, AND REQUEST FOR APPROVAL OF PLAN FOR AUGMENTATION Page 10 of l2 iii) Out -of- priority evaporative depletions: Depletions from the McCurter Lake Pit Well will equal 61.83 a.f. annually. A table outlining the monthly evaporative depletions, as well as the timing of their impacts on the Gunnison River, is attached as Exhibit 10 iv) Out -of- priority industrial depletions: The depletion associated with industrial use is 15.74 a.f. annually, which, due to delayed impacts, could result in a maximum of 16.39 a.f. depletions to the Gunnison River. A table outlining the extent and timing of those depletions is attached as Exhibit 11. v) Operation of the plan: Applicant will augment out-of-priority depletions from evaporation and industrial use through the dry -up of 37 acres of formerly irrigated land under the East Creek Ditch and the Star Enlargement of the East Creek Ditch, as well as tluough the dry up of 77 acres of formerly irrigated land under the Wadlow Pumping Plant. Although the potential call period for the Senior Redlands Right during the 2002 -2003 drought did not include any call days during the months of May - October, Applicant has dedicated 34.56 a.f. of dry -up credits from the East Creek Ditch to provide protection in the event of a drought exceeding the severity of the 2002 -2003 event. Similarly, although the potential call period for the Junior Redlands Right during the 2002 -2003 drought did not include any call day during the months of July- October, Applicant has dedicated 7.22 a.f. of dry -up credits under the Star Enlargement of the East Creek Ditch and 60.71 a.f. of dry -up credits under the Wadlow Pumping Plant to protect against more severe future droughts. A table outlining the monthly allocation of dry -up credits is attached as Exhibit 12. A table outlining the water balance for evaporative depletions and industrial use is attached as Exhibit 13. Applicant will address out -of- priority depletions during the nonirrigation season through a water supply contract with the Bureau of Reclamation for releases from Blue Mesa Reservoir, As shown in the attached Exhibit 13, the water supply contract necessary to address out -of- priority depletions during the non - irrigation season will require Applicant to obtain a water supply contract from Blue Mesa Reservoir for 20 a.f. Historic irrigation return flows including surface runoff and deep percolation associated with the 37 -acre dryup will be maintained to ensure downstream water rights holders are protected from injury. Irrigation diversions formerly taken to irrigate the 37 acres will
