Delivery of Depletion Credits <br /> Prior to exchange to Pueblo Reservoir, the water attributable to the 635 fallowed shares will be <br /> delivered to the headgate of the Catlin Canal and measured through the ditch flume.The portion of <br /> the delivery attributable to ditch losses (canal losses of 10.43% and lateral losses of 3.5%) will be <br /> left in the ditch. The remaining water will be measured through the flume at the Timpas Creek <br /> augmentation station or the Crooked Arroyo augmentation station and returned to the Arkansas <br /> River at the locations identified above,wherefrom the available depletion credits will be exchanged <br /> to Pueblo Reservoir for use by Colorado Springs. <br /> Stepped exchanges may be used when exchange potential exists in only a portion of the reach <br /> between the augmentation stations and Pueblo Reservoir. For example, if there is exchange <br /> potential from the Timpas Creek augmentation station to the Colorado Canal, but not from the <br /> Colorado Canal to Pueblo Reservoir, water may be exchanged to the Colorado Canal for delivery to <br /> Lake Meredith. This water may later be released and exchanged to Pueblo Reservoir when <br /> exchange potential exists from the Lake Meredith point of delivery to the Arkansas River to Pueblo <br /> Reservoir. Applicants would only operate stepped exchanges into storage locations for which <br /> Applicants have obtained a right to do so. Use of stepped exchanges, while desirable, is not <br /> necessary for the proposed pilot project operations. <br /> 3. Return Flow Obligations <br /> During the term of the Colorado Springs/Super Ditch Pilot Project, return flow obligations will be <br /> met through portions of the headgate diversions of water available from the fallowed lands and <br /> releases from Pueblo Reservoir and other fully consumable sources available to Colorado Springs. <br /> When depletion credits are in excess of the return flow amounts owed for that month, the excess <br /> depletion credits may be exchanged to Pueblo Reservoir for all approved uses by Colorado Springs <br /> or for replacement of future return flow obligations. The administrative reach for the exchange will <br /> extend approximately 90 miles from the confluence of Timpas Creek and the Arkansas River, or 94 <br /> miles from the confluence of Crooked Arroyo and the Arkansas River, upstream to the outlet works <br /> of Pueblo Reservoir. Water exchanged to Pueblo Reservoir and later released to meet return flow <br /> obligations is subject to evaporation while in Pueblo Reservoir. Lagged return flow obligations <br /> associated with Colorado Springs' use of the water available from the fallowed lands may also be <br /> met through releases of fully consumable water from Lake Meredith, previously stored water in <br /> Pueblo Reservoir, or by utilizing reusable return flows at the mouth of Fountain Creek.Transit losses <br /> as assessed by Division 2 will be included from the point of release. It is proposed that winter return <br /> flow replacement releases be booked over to the Winter Water program and/or released to the <br /> stream as determined necessary to replace such return flows to the appropriate water rights. <br /> These replacement operations are described in detail in the attached Letter Agreement between <br /> the Super Ditch and Colorado Springs.To the extent possible,Colorado Springs intends to exchange <br /> the deep percolation return flow credits delivered to Pueblo Reservoir into its municipal system <br /> under the decree entered in Case No. 05CW96 (where such water will be fully consumed for <br /> municipal uses), and then replace the deep percolation return flows owed to the Arkansas River by <br /> releasing to the Arkansas River other fully consumable sources as described in this section.
