Introduction <br /> <br />This report describes a plan to replace the stream depletions attributable to pumping of <br />tributary ground water in the Arkansas River Basin by 332 active wells included by membership in <br />the Arkansas Groundwater Users Association (AGUA), The plan covers the period of April I , 1997 <br />through March 31, 1998 (the 1997 plan year) and has been prepared in accordance with Rule 14 of <br />the Amended Rules and Rel1ulations Govemin~ the Diversion and Use ofTributal)' Ground Water in <br />the Arkansas River Basin. Colorado (the Rules), Division of Water Resources, September 27,1995, <br />and the Requirements for 1997 Arkansas River Replacement Plans, Division of Water Resources <br />memo dated January 28, 1997. This report includes: <br /> <br />. Quantification of stream depletions that will accrue during the 1997 plan year due to well <br />pumping during the 1996 plan year. Wellhead depletions! are based on actual pumping <br />amounts for June 1996 through January 1997, and on estimated pumping amounts for <br />February and March 1997. <br />. Quantification of projected 1997 plan year pumping, wellhead depletions, and stream <br />depletions that will accrue during the 1997 plan year as well as those that will accrue after <br />the 1997 plan year. <br />. Description of proposed replacement sources available during the 1997 plan year. <br />. Comparison of monthly replacement requirements and replacement sources availability. <br />. Quantification of post 1997 plan year depletions to be covered by a letter of credit. <br />. Discussion of replacement requirements for four separate substitute water supply plans <br />(SWSP) which will be administered by AGUA. Approval of these SWSP's is separate from <br />this application. <br /> <br />Appendix A-I contains an alphabetized listing of the wells included in AGUA's 1997 <br /> <br />Arkansas River Replacement Plan. In Appendix A-2, the same list is ordered according to Structure <br /> <br />ID number. Appendix B contains a detailed listing of every well in the plan including it's projected <br /> <br />annual use, total depletion, and estimated plan year and post plan year replacement requirement. <br /> <br />Wellhead depletions are equal to well pumping times a depletion factor as described in Section 5.1 <br /> <br />G:\3177 _OO3\REPORTS\AGUA97 _l RPT <br /> <br />1 <br /> <br />Printed FebT\Jary27, 1997 <br />
