U00730 The Service has indicated that: (1) the source of water for the 10,825 acre-feet interim/permanent commitment during the late summer and early fall will be according to the contracts recently entered into (Colorado River Conservation District and Colorado Water Conservation Board, 2000 and Denver Water and Colorado Water Conservation Board, 2000), and (2) these sources of supply are independent from sources of supply which will be used for the 20,000 acre-feet average annual commitment to be used for augmenting spring peak flows. 2.3.7 Scoring An acre-foot of water released or otherwise made available will be counted or credited as meeting the target flows when: 1. The flow at the head of the 1S-Mile Reach is between 12,900 and 26,600 cfs; 2. The acre-foot of water would not have been available at that point in time under baseline conditions without the program and projects to provide the average annual 20,000 acre-feet; and 3. The acre-foot is made available during the 10-day period surrounding the peak spring flow; or 4. The acre-foot was not used in the spring, the acre-foot cannot be carried over in storage until the next spring, and the acre-foot is used to augment low flows during the July to October period. In order to be scored as having been available, water will be scored at the source of delivery, not at the IS-Mile Reach. Throughout this report, the term, "average annual 20,000 acre-feet" will be used to indicate the target for this program. It must be emphasized that this is an average of 20,000 acre-feet per year added to the spring hydrograph peak in those years in which the forecast flow at the head of the 1S-Mile Reach is between 12,900 and 29,600 cfs. The calculation to determine the average annual delivery will be based on those years in which the peak flow is expected to be between 12,900 and 26,600 cfs. . 2.3.8 Piscatorial Purposes A water right decreed for piscatorial purposes may be required for implementation of several of the alternatives analyzed in this report. It may be necessary, therefore, to obtain a junior water right for piscatorial purposes in order to implement those alternatives where there is no existing water right for piscatorial purposes. The necessity and frequency of obtaining such a junior must be determined before implementing any of the alternatives.
