<br />. <br /> <br />days in September, squawfish were apt to forage within a run/riffle sequence. During <br /> <br />low flow events, larger and deeper pools will presumably offer more foraging potential <br /> <br /> <br />than smaller pools. Burdick (1996) proposed that the maximum depth of a riffle should <br /> <br /> <br />be at least 1.0 ft of depth to provide unrestricted passage. The median riffle had a 1.0 ft <br /> <br /> <br />maximum depth at a flow of 123 cfs for the riffles surveyed in this study (Anderson et al <br /> <br /> <br />1998). Flows under 111 cfs appear to have high potential for restricting squawfish <br /> <br /> <br />movements to within a single or low number of riffle/run sequences. At flows over III <br /> <br /> <br />cfs, fish movements should not be a problem on at least half the riffles. <br /> <br />32 <br />
