<br />" <br /> <br />. <br /> <br />. <br /> <br />2. Es"irna"e s"rearn flows a" key s"rearn loca"ions. <br /> <br />a. Below confluence with the Swan River. <br />b, From confluence wi"h Swan River "0 Bar"on Gulch, <br />c, From Breckenridge "0 Goose Pas"ure Tarn, <br /> <br />3. Factor out existing and future water righ"s to <br />calculate real minimum stream flows. <br /> <br />a. Compare predic"ed hydrology with the instream flow <br />rates identified in the Green Mountain Water <br />Marr.e"ing Program Final EIS. Indica"e how often <br />and when the predicted stream flows drop below <br />those rates under preseD" and future conditions. <br /> <br />b. Compare predicted hydrology with the minimum of one <br />day "hree year and thirty days "hree year (lQ3 and <br />30Q3) rates identified in the NPDES permit(s) for <br />discharger(s) on the Blue River. Indica"e if the <br />lQ3 and 30Q3 rates are adequate under present and <br />future conditions. <br /> <br />c. Evaluate the amount of augmentation water needed to <br />meet the present and 'future water uses and the <br />amount necessary to protect the instream uses for <br />the most critical stream reaches. <br /> <br />4. Augmentation Sources. <br /> <br />a. Review the existing operation of the Goose Pasture <br />Tarn. Indicate the operational changes possible so <br />that the reservoir could be used in an optimum <br />manner to meet in-basin demands during the most <br />critical periods. Investigate the legal or other <br />institutional changes that would have to be made to <br />change the operation of the Tarn. <br /> <br />b. Review the cost and feasibility of enlarging the <br />capacity of the Tarn concurrently with the <br />reconstruction of the spillway. Analyze how much <br />additional water is available from such an <br />enlargement and at what ,=ost it could be made <br />available. <br /> <br />c. Investigate the preliminary feasibility of smaLl <br />reservoir sites in the Upper Blue Basin above the <br />confluence with the Swan. Sites that have been <br />previously identified include Indian Creek, Upper <br />Mohawk. "100 sites identified by Lee Brill. and a <br />site identified by the Blue River Water District, <br />The analysis should incl11de estimates ~o= storable <br />inflow. cost, wha"ever geo"echnical analysis is <br />possible without field testing, and review of <br />environmental '1fatal ~la~'s.~ <br /> <br />-2- <br />
