<br />t representative reach for each size-class could serve to represent that <br />size-class adequately for a reconnaissance analysis of impacts due to <br />flow manipulation. <br /> <br />~ <br />-..:t <br />tv <br />tv <br /> <br />. <br /> <br />. <br /> <br />The selection and conceptual simulation of stream reaches representative <br /> <br /> <br />of various size-classes within a RAA is paramount to the successful <br /> <br /> <br />app 1 i cat i on of the methodology. The methodo 1 ogy out 1 i nes the procedure <br /> <br /> <br />for selection as follows: <br /> <br />1. From maps, locate USGS gaging stations and additional stations as <br />appropri ate. <br /> <br />2. <br /> <br />Stratify all streams into four to six size classes considering (a) <br /> <br /> <br />streams with entire length falling with the RAA; (b) streams cross- <br /> <br /> <br />ing the RAA; (c) streams flowing into the RAA; and (d) streams <br /> <br /> <br />orignating in the RAA but flowing into other RAA's. <br /> <br />3. "Select" one candidate stream to provide the initial data for each <br />stratified class. <br /> <br />4. Obtain physical stream data from records for each candidate stream. <br /> <br />5. Describe the candidate reach for each stratified stream class within <br /> <br />each RAA. <br /> <br />10 <br />
