However, the winter instream <br />flow recommendation was reduced to 0.85 cfs (11/15 - 3/14) based on the water availability analysis. . <br />The DOW believes the lower flow recommendation will still preserve the natural enviromnent. <br />· CWCB staff has conducted a water availability analysis and determined these amounts are available for <br />the Board's appropriation. <br />· CWCB staff has determined that adequate water supplies exist such that the natural enviromnent may be <br />preserved without limiting or foreclosing the exercise of valid existing water rights. <br /> <br />CONSULTATIONS: <br /> <br />DOW: Jay Skinner <br /> <br />8/1/96 <br /> <br />DWR: Steve Witte <br /> <br />8/1/96 <br /> <br />eCWCB STAFF: <br /> <br />Prepared By: Uppendahl <br /> <br />1/15/98 <br /> <br />Reviewed By: Espegren <br /> <br />1/20/98 <br />
