However, the Winter instream <br />flow recommendation was reduced to 0.2 cfs (8/15-4/14) based on the water availability analysis. The <br />DOW and DPOR believe the lower flow recommendation will still preserve the natural environment. <br />· CWCB staffhas conducted a water availability analysis and detennined these amounts are available. for <br />the Board's appropriation. <br />· CWCB statfhas determined that adequate water supplies exist such that the natural environment may be <br />preserved without limiting or foreclosing the exercise of valid existing water rights. <br /> <br /> CONSULTATIONS: <br /> DPOR: Paul Flack 713/1996 DWR: Dick Stenzil 9/23/1996 <br /> DOW: Jay Skinner 713/1996 <br /> CWCB STAFF: <br />e Prepared By: Uppendahl 1/15/98 Reviewed By: Espegren 1120/98 <br />
