of river water used for irrigation. Colorado is developing models using a Glover analysis to <br />account for such return flows. In the future based on this modeling, Colorado will present to the <br />Governance Committee for consideration new transit loss factors for routing unprotected the net <br />accretions and depletions for determining average monthly cumulative effects for mitigation <br />purposes. <br />Colorado has begun the re-regulation through managed groundwater recharge for mitigating the <br />net depletions of Colorado's Plan for Future Depletions (CPFD). Two recharge wells next to the <br />river began pumping in January 2007 at the Colorado Division of Wildlife's Tamarack Ranch <br />recharge project and a total of eight wells are pumping as of the first week in March 2007 at <br />Tamaraclc Ranch and will continue until called out. In addition, Colorado has committed to paying <br />the pumping on recharge wells pumping into the Peterson Ditch for recharge this spring of 2007 <br />depending upon South Platte river calls and Compact requirements. Colorado is also developing <br />leases with private recharge projects for the lease of their excess recharge accretions that result <br />from diversion of net monthly accretions from the CPFD and that are not needed for well <br />augmentation in May and June.
