Whitmore indicated she will be developing a time line/schedule for future EA AOP development. <br />This will be done in an effort to help clarify some of the timing and procedural situations that <br />came up during the first year of EA establishment. She'll provide a draft to the EAC when done. <br />EA Accountin <br />Hayden provided a draft spreadsheet to be used to account for EA contents on a monthly basis <br />and indicated that NEDWR would welcome input on modifications. He asked two EA-related <br />questions; 1) Because contributions to the EA will not be credited until the end of the month, can <br />EA water, not yet credited, be used during the month?; and 2) If the EA goes to zero during a <br />month, how will its share of seepage loss be accounted for? The group surmised that the first <br />question may require additional discussion. For the second question, when the EA hits zero, its <br />share of seepage losses ends. Committee members should provide comments on the draft <br />spreadsheet to Hayden. <br />Review of Comments and Draft EA 2000 Annual Operating Plan <br />Tebbel dispersed a copy of Paul Currier's recommendations for EA releases. Whitmore gave a <br />summary of EA AOP comments that were received prior to the meeting. She will provide copies <br />of the comments to EAC members. <br />Tullis asked if effects from EA releases will be monitored. Monitoring of EA release effects, <br />will eventually be covered under the monitoring and research component of the Program. Also, <br />past and current information is to become part of the baseline used to compare changes that result <br />from Program activities. The group agreed that, until the Program is implemented, any <br />information obtained on effects from EA releases will be incidental. <br />Fish and Wildlife Service (FWS) flow recommendations were discussed. The group agreed that, <br />although FWS flow recommendations are not accepted by all, the Cooperative Agreement <br />recognized that the FWS will use them until new information indicates that they should be <br />changed and arguing their merits during the AOP discussion was unproductive. <br />Several attendees recommended that EA water not be used to create or augment pulse flows in <br />2000 because high water conditions and pulses in recent years have resulted in minimal in- <br />channel vegetation establishment. It was also mentioned that trying to achieve mathematical <br />averages (augmentation of 5 and 10 year running averages for exceedances during pulse flow <br />periods) will not provide additional benefits because sediment is already actively sculpting the <br />channel as a result of high flows. Whitmore explained that during the period of record, including <br />the last 5 years, there have been consistent shortages to recommended pulse flows and that the <br />FWS will continue to prioritize looking for opportunities to augment pulses to reach 5 and 10 <br />year ruruling averages. She explained that the longer duration pulse flows promote certain river <br />processes and provide benefits that shorter duration pulses or the recent occurrence of higher <br />flows do not. <br />It was suggested that a description of how EA water will be protected be included in the EA <br />AOP. The group agreed that the state of Nebraska is responsible for protecting EA water to the <br />central Platte and it is not an issue that needs to be addressed in the EA AOP. <br />2
