'maximum displacement is defined as the maximum distance moved from release point foilowin$ release either upstream or downstream during the entire
monitoring period.
"final displacement is defined as the distance from the release point following implantation of the radio tag to the last contact point: (+) represents upstream
movement, (-)represents downstream movement.
`entered the Grand Valley Water User's Canal from the Colorado River at river mile 193.7. The radio tag was located in the sediment basin immediately up-canal of
the automated trash rack in the Grand Valley Water User's Canal at 17-3/4 Road on 4 December 2001. Fish is presumed dead.
