Projected post 2020 - <br /> 2021 plan year depletions are calculated to be 15.3 acre-feet. <br /> REPLACEMENT <br /> For the April 2020 through March 2021 period, the Applicant has leased 64.90 acre-feet or more of <br /> fully consumable replacement credits from the Arkansas Groundwater Users Association ("AGUA") <br /> available pursuant to a long term agreement dated March 19, 2018 (attached), which will be used to <br /> replace depletions from mining. The credits will be generated through the delivery of fully <br /> consumable water available to AGUA from the Board of Water Works of Pueblo, from the City of <br /> Aurora, or from the Pueblo West Metropolitan District, to AGUA's Excelsior Recharge Ponds located <br /> immediately west of Chico Creek.
