~ 000318 e e I (~~ I \~~ . &# ~'J,; ~ u'~,.y 0) I \~ Any type flow year will benefit from augmentation. "Therefore all peak flow recommendations in the IS-mile reach should be considered." (Does this mean that all augmentation of peak flows in the IS-mile reach should be considered for counting toward delivery of the 20K?) Water moved from a period of excess to a period of shortage should be counted towards the 20K. . Water moved from the winter to spring would count in delivery of the 20K on an average annual basis. . Water delivered in excess of the flow recommendations would not count. (Does this mean that water delivered in excess of the 20K in any year will not count? Or, that water delivered in excess of some specific flow recommendations (e.g. water in excess of SOOO cfs during the first week of April would not count?) l . Use April-July targets from page 8, Appendix D, Preliminary Biological Opinion. There obviously needs to be more discussion concerning this matter, but the above represents a start. 6. Flow Targets. The following is from the February 2 Maddux to Seaholm memo: · The Service's first priority for delivery of water would be to add to the spring peak during the same IO-day period that the coordinated reservoirs operations program is trying to add to the peak. (This yields support to the need for a daily time step model during the Spring peak runoff period.) Ifall of the 20K could be provided during the peak:, it would not be necessary to provide any water during other periods. · The Service's second priority is to provide the water in May-June. · Third priority is to deliver water between July 15 and August 31 when deliveries from other sources are less certain. · Fourth priority is in September and October. 7. Flexibility of Meeting Flow Targets. The following is an interpretation of the Service's February response to Randy's questions concerning allowable flexibility in meeting the flow targets: · Adaptive management should be employed whereby the flow target and the flexibility in meeting this target would be identified and implemented on a year to year basis depending on the hydrologic conditions in a specific year. Actual deliveries would be made in a specific year based on established guidelines and general criteria for making water available. These guidelines and criteria would be established as part of the Water Availability Study. · Ranges of permissible water deliveries and timing of deliveries would be set through agreements and contracts. The ranges and timing of permissible water deliveries would be established in the Water Availability Study and later incorporated in contracts and agreements.
