Table D.2. (cont'd). Monthly sampling summary of sub-adult and adult Colorado squawfish captured and positively
sighted while electrofishing in the Redlands Diversion Dam plunge pool (river mile [RM)
3.0) and in the 2.2-mile reach of the Gunnison River immediately downstream between the
Redlands Diversion Dam plunge pool and Colorado River confluence, 1979-1995. Note: catch
effort is total catch per unit effort (total fish divided by total effort); ?=unknown as
to whether sampling was conducted during these months; NS=not sampled; NR=effort was not
recorded, thus unable to calculate total catch per unit of effort.
