<br />AGENDA ITEM Ib <br />SPECIAL BOARD MEETING <br />December 13. 1995 <br />ATIACHMENT 1 <br />KEY DECISION ISSUES <br />Y AMPA RIVER <br /> <br />1. Base Flow Amounts: <br />Are the amounts acceptable? Staff recommends changing some of the Yampa base <br />flows to more closely resemble the hydrograph as defined by the adjustedflows shown in <br />the physical water availability study. Typically, the Service's recommended base flows <br />during the non-runoff months are at the 80% exceedance levels or greater as defined by <br />the Board's physical water availability study (meaning that today water is in the stream <br />at these flow rates at least 80% of the time or more). Our suggested changes are aimed <br />at mimicking a natural hydrograph that will be present 90-95% of the time since the <br />Service has indicated they may choose not to augment winter base flows. However, the <br />amounts in the final notice may be acceptable for filing purposes given that they could <br />be adjusted downward as the Carve Out is distributed. <br /> <br /> Oct. Nov. Dec.

Recoverv Flow Amounts: <br />Should the Recovery Flow be a numeric value as described in the Final Notice or <br />for the flows remaining after the Carve Out is in full use? This is the most <br />controversial part of the application; staff recommends that the Board adopt the later <br />approach which has been described in various forms (e.g. "the streamflow remaining <br />after humans have totally consumed the Carve Out" or "Flows remaining after the <br />Carve Out isfully developed"). If the Board chooses numeric values, terms and <br />conditions which reflect afrequency of enforcement consistent with the Service's <br />recommendations will need to be developed. <br />How should administration be accomplished? Staff recommends that this be <br />negotiated during water court proceedings. <br />Do not call for right if such could cause flooding. Staff recommends that this <br />condition be negotiated during water court proceedings. The Service would like to see <br />some flooded bottom lands, but, the Board staff is concerned that such action not result <br />in any property damage. <br /> <br />3. Carve Out: <br />Are the amounts acceptable? A annual Carve Out of 52,000 acre feet appears to be <br />acceptable and staff recommends that an annual Carve Out in this amount be provided <br />for. <br /> <br />1 <br />
