Table K.4. Radiotelemetry data for four adult Colorado pikeminnow (CS) in the Upper Colorado (CO) and Gunnison
(GU) rivers, 1999 that were caught in the fish trap of the Redlands Diversion Dam and released
immediately upstream of the fishway in August and September 1999. Note: the number of days fish
were contacted included both those recorded by automated data logging stations and by boat;
RM=river miles; 15- and 18- refers to the 15-Mile and 18-Mile Reaches of the Upper Colorado River
near Grand-Junction, CO; Ruby/Horsethief canyons: river mile 130.5-152.7. Fish were equipped with
10 gram, LOTEK® model MCFT-3FM radiotags.

a upstream of the Redlands Diversion Dam (river mile 3.0).
b downstream of the Redlands Diversion Dam: the lower Gunnison River downstream of the Redlands Diversion Dam
to the Colorado River confluence--river mile 3.0-0.7..
C maximum displacement is defined as the maximum distance moved from release point following release either
upstream or downstream during the entire monitoring period.
d final displacement is defined as the distance from the capture point following implantation of the radiotag
to the last contact point: H represents upstream movement, (-) represents downstream movement.
