<br />spring of 1992 and 4000 cfs in the spring of 1993. Clearly, the results of the <br />VI tagging studies from 1991 through 1993 indicate that the "wild" stream-reared <br />trout do not move very far under any discharge scenario. Nonetheless, the higher <br />peaks and extended duration of managed spills in 1992 and 1993 certainly <br />facilitated freer movement of fish throughout the river below the dam. <br /> <br />Table 13.
