CONCLUSIONS

1 .

Humpback chub and Colorado pikeminnow occupied the lower 15 km of the
Little Snake River in June and July during runoff and telemetered humpback
chub moved from the Little Snake River to the Yampa River in early August
just before baseflow and as temperatures cooled in the Little Snake River.

2.

Humpback chub moved relatively long distances (32 and 39 km) from the
Little Snake River to the Yampa River and occupied the Little Snake River
during their spawning period.

3.

Native flannel mouth sucker, bluehead sucker, and roundtail chub composed
the majority of the large-bodied fish community and nonnative channel
catfish, white sucker, and common carp were rare in the Little Snake River at
all seasons and reaches. Composition of large-bodied species
(adults L 200 mm total length) changed minimally among seasons or sites.

4.

Nonnative sand shiner and redside shiner and native speckled dace composed
the majority of small-bodied species collected, but many small-bodied
nonnative species typically abundant in other rivers were rare in the Little
Snake River. Composition of most small-bodied species (adults size
< 200 mm total lengthl changed minimally among seasons or sites, except
for composition of redside shiner that declined in autumn and varied by reach
and red shiner that also varied by reach.
