However, the winter instream <br />flow recommendation was reduced to 0.6 cfs (10/15-5/:11) based on the water availability analysis. The <br />DOW believes the lower flow recommendation will still preserve the natural environment. <br />· CWCB staffhas conducted a water availability analysis and determined these amounts are available for <br />the Board's appropriation. <br />· CWCB staffhas determined that adequate water supplic:s exist such that the natural enviromnent may be <br />preserved without limiting or foreclosing the exercise ofvalid existing water rights. <br /> <br />CONSULTATIONS: <br /> <br />DOW: Jay Skinner <br /> <br />8/1/96 <br /> <br />DV1R: Steve Witte <br /> <br />8/1/96 <br /> <br />CWCB STAFF: <br /> <br />_prepared By: Uppendahl <br /> <br />1/15/98 <br /> <br />Re,,jewed By: Espegren <br /> <br />1/20/98 <br />
