• An under run in subbasin 1, 4 or 6 will result from lack of water supply in the <br />subbasin. <br />• An under run in subbasin 2 or 3 could result from lack of water supply in the <br />subbasin or from an overrun in subbasin 1 or 2. <br />• An under run in subbasin 5 could result from lack of water supply in the <br />subbasin or from an overrun in subbasin 4. <br />Conclusions: <br />• Under runs in subbasin 1 do not contribute to or result from overruns in any <br />other subbasin, but because the overall effect of any net overrun in subbasins <br />1 and 2 is to reduce storage in Pathfinder for North Platte contractors, under <br />runs in subbasin 1 can be used as an offset for an overrun in subbasin 2. They <br />should not, however, be used as an offset for overruns in any other subbasin. <br />Routing of an under run in subbasin 1 needs to reflect only conveyance losses <br />to Whalen. Routing below Whalen is not needed. <br />• Similarly, an under run in subbasin 2 can be used as an offset for an overrun <br />in subbasin 1 but not for any other subbasin. Routing is needed only to <br />Whalen and should reflect conveyance losses only. <br />• Under runs in subbasin 3 do not contribute to or result from overruns in <br />subbasins 4, 5, or 6 and should not be used as offset for overruns in any of <br />those subbasins. Also, if net overruns in subbasins 1 and 2 are replaced at <br />Whalen, under runs in subbasin 3 will not result from overruns in subbasins 1 <br />or 2. Therefore, they should not be used as offsets for any net overrun from <br />subbasins 1 and 2. No routing is necessary. <br />• Under runs in subbasin 4 do not contribute to or result from overruns in any <br />other subbasin but the net effect of overruns and under runs in subbasins 4 and <br />5 will be absorbed by Grayrocks reservoir much like Pathfinder absorbs the <br />net effect of overruns and underruns in subbasins 1 and 2. Therefore, there <br />are no state line impacts from underruns (or overruns) in subbasin 4 except to <br />the extent spills from Grayrocks are affected. When spills are affected, under <br />runs from subbasin 4 could be used as an offset for an overrun in subbasin 5, <br />but should not be used as offsets for overruns in any other subbasin. Under <br />runs in subbasin 4 should be routed to subbasin 5 using normal conveyance <br />losses. <br />• Under runs in subbasin 5 do not contribute to or result from overruns in <br />subbasins 1, 2, 3, or 6. Such underruns are largely absorbed by Grayrocks <br />reservoir as described above and should not be used as offsets for overruns in <br />any of subbasins except subbasin 4. Under runs in subbasin 5 do not need to <br />be routed downstream. <br />• Under runs in subbasin 6 do not contribute to or result from overruns in any <br />other subbasin, therefore should not be used as offset for overruns in any of <br />those subbasins and do not need to be routed downstream. <br />Baseline 2, Subbasin 1 Overruns <br />Assumptions: <br />• Same as for Baseline 1, subbasin 1, except that overruns in this subbasin can <br />also occur during the non-irrigation season. The effect normally would be to <br />4
