The capture of a single humpback chub (Gila
<br />cypha) in Cross Mountain Canyon (Aug 1982) is
<br />described. This was the first report of this
<br />rare endangered species in the Yampa River
<br />since 1962 and the most upstream capture
<br />record. The capture of a Colorado squawfiah
<br />(Ptychocheilus lucius) is also reported.

<br />Fish were collected in the lower Yampa Canyon
<br />of the Yampa River and near the Colorado-Utah
<br />border on the Colorado River is 1981 and 1982.
<br />More introduced species than native species
<br />were collected, and redaide shiners and fat-
<br />head minnows were the predominate species in
<br />the samples. Colorado squawfish young-of-the-
<br />year were collected at both sites.

<br />1980-83 in the Yampa River. Estimates of

<br />ted to flow/temperature regimes are offered.
<br />Observations on exotic species spawning success
