These demands were imposed in the following <br />distribution: <br /> <br />Oct Nov Dec Ian Feb Mar Apr May Iun Iul Au!!

The resulting <br />depletions in the modeling were very close to these demands. The average depletions over the <br />study period were 58,974 and 117,915 acre-feet per year, respectively. The water rights for the <br />future depletions were given an administration number slightly senior to the Service <br />recommended fish flows for the IS-Mile Reach, <br /> <br />Recovery Action Plan Scenarios <br /> <br />The following Recovery Action Plan items were modeled, as per modifications made by Ross <br />Bethel of Leonard Rice Consulting Water Engineers: <br /> <br />> Grand Valley Water Management components, which include a reduction in <br />irrigation demand under the Grand Valley Project, and an operational bypass of <br />9,000 acre-feet/year at the GVP headgate <br /> <br />> GVP Power demand with a junior priority during summer months <br /> <br />> Orchard Mesa Check operated to only benefit the Grand Valley systems <br /> <br />> HUP Surplus deliveries to the IS-Mile Reach <br /> <br />> Wolford Mountain Reservoir releases from the 6,000 acre-feet fish pool to the <br />IS-Mile Reach <br />
