Eight pikeminnow that were found in the fish trap in 1998 <br />were recaptures. Some noteworthy facts were obtained from <br />three of these fish. Two pikeminnow found in the fish trap <br />in 1997 were again found in the trap in 1998. Also, from <br />recapture data, another pikeminnow that used the fish ladder <br />in 1997 and released upstream of the dam, sometime moved <br />downstream over Redlands Diversion Dam following its release <br />because it was recaptured in a trap net at 29.5/8 Road pond <br />on the Colorado River (river mile 174.4) in May 1998. <br /> <br />Three pikeminnow collected in the trap in 1997 were <br />recaptures and had been previously captured in the Colorado <br />River downstream of Moab, Utah. <br /> <br />CAp.4B.3 <br />
