of which were used to explain a changing native / non-native species
composition and compile species accounts to provide a more critical
analysis of the impact on the fish community.
While studying the fishes of the White River a second objective
became apparent due to the fact that the adult fish community was
found to be more diverse below Taylor Draw Dam than above the
reservoir before as well as after impoundment. To explain this
difference, selected habitat components and channel morphometrics were
analyzed and correlated to this intrinsic variation in fish species
diversity.
The final objective of this study was to elucidate general
movement patterns of White River fishes through a three year mark and
recapture study. Although five species of fish were tagged (Appendix
Table 4.6 and Appendix Figure 4.4), the flannelmouth sucker (Catostomus
latiQinnis) was the only species recaptured in sufficient numbers to
analyze. To determine if impoundment affected the average net
movements of flannelmouth suckers, values were compared for various
- length classes before and after completion of Taylor Draw Dam.
