<br />...... "!. 7 '.n <br />\jJt JJ <br /> <br />The Report <br /> <br />This report is a summary of data that will help Reclamation, state <br />agencies, other federal entities, and the public understand what <br />low flows in the San Juan River can mean to those with an interest <br />in the river and the ways in which it is used. The technical data <br />gathered as a result of this Test is included as attachments. The <br />aerial photography and vegetation mapping data is not available <br />at this time; however, it will be available for the draft EIS which is <br />scheduled for release in early 2002. <br /> <br />II. How Reclamation Conducted the Test <br /> <br />Methods <br /> <br />Using input from the public, earlier studies, and agency expertise, <br />emphasis for the Test was placed on certain resources: irrigation, <br />domestic, municipal and industrial water diversions; economics; <br />recreation; the trout fishery; water quality; and others. <br /> <br />The Test period of 5-10 days was selected as a span in which basic <br />physical changes could be observed and, to some degree, <br />extrapolated to longer-term conditions. A shorter length of time <br />would not allow the river to reach equilibrium after flow changes <br />occurred in order to conduct testing, and a somewhat lengthier <br />period would not provide significantly more data concerning long- <br />term dam release patterns. <br /> <br />Termination guidelines were in place during the Test if significant <br />impacts were observed or if public health or safety were <br />compromised. <br /> <br />Summer Low Flow Test Report - November 2001 <br /> <br />-3- <br />
