Colorado pikeminnow to observed growth in an independent investigation. Then the model was used to
evaluate the potential for overwinter survival of age-0 Colorado pikeminnow to be influenced by changes
in fish activity.
STUDY OBJECTIVES
Each component of the Flaming Gorge Winter study had specific objectives to address
concerning the effects of winter operations of Flaming Gorge Dam on the survival, distribution, and
nursery habitats of age-0 Colorado pikeminnow. In Table 1, study objectives for each project are
presented and the reader is directed to the relevant draft report. The Colorado River Fish Project-Vernal,
Utah, was responsible for conducting field investigations (i.e., population estimates, winter fish sampling,
and monitoring stage fluctuations) in the alluvial reach occupied by age-0 Colorado pikeminnow.
Colorado State University was responsible for characterizing movement rates under simulated winter
conditions; and developing and evaluating a bioenergetics model for age-0 Colorado pikeminnow.
