Nine streams were examined for populations of
<br />Salmo clarki pleuriticus. Using a combination
<br />of meristic characters to determine degree of
<br />purity, the streams were rated for purity of
<br />the subspecies. Management recommendations
<br />were made based on the ratings.

<br />Report of studies on 9 sites in the upper White
<br />River during 1962-63. Rainbow, brook, brown,
<br />and cutthroat trout were reported from Sweet-
<br />water Creek, and South Fork White River. This
<br />report documented the unlikelihood of pure
<br />Colorado cutthroat trout in the sites studied.

<br />An overview of the recognized impacts of the

<br />bonytail--G. elegans, and razorback aucker-
<br />Ryrauchen teaanus) are used as case studies.
