If not, why not?: <br />Yes, eWCB 10 cfs year round instreamflows will meet USFS needs on both streams. <br />However, USFS also wants flushing flows (70%-120% of Bankfull) on both streams for <br />some specified period between May 15 and July 15 each year to maintain native aquatic <br />habitat and move sediments. <br /> <br />If water is developed from stream, what protections does the USFS know would have to <br />be provided? None identified <br /> <br />Is potential development compatible with USFS needs? If not, why not? <br /> <br />RECOMMENDATIONS: <br />(i.e. can QP's be moved, CWCB instream flows acceptable, etc.) <br />Delete current QP and establish new QP' s on both Middle and South Cottonwood <br />Creeks as described above. Use the CWCB 10 cfs year round instreamflows on each <br />stream to quantify the USFS instreamflow baseflow claims. Have USFS define (general <br />hydrographs) what the flushing flow amounts should be and the time during which they <br />want it protected. Limited upstream exchange potential is required with the new QP <br />locations. <br /> <br />ATTACHMENTS: List of attendees at the August 21, 1996 meeting and stream maps and lists <br />of water rights in the area provided by the SEO. <br /> <br />RANDYlC:\MSOFFICE\ WINWORDlD2FSRWR.FOR <br /> <br />2 <br /> <br />I <br />" I <br />J~,I <br />
