<br />Marked seasonal variation occurred in the density of macroinvertebrates in Trout Creek,
<br />Colorado. Aquatic insects composed over 90% of the fauna; caddisflies (Trichoptera) were
<br />the dominant forms. Diversity did not differ significantly throughout the study area.
<br />Water quality diminished primarily during spring runoff and the invertebrates appeared to
<br />tolerate the short period of water degradation. The buffer zone between the mine area
<br />and Trout Creek apparently decreased the effects of mine drainage on the macroinvertebrate
<br />community.

<br />
<br />Fish and macroinvertebrates were sampled in the Yampa and White Rivers between July 1975
<br />and September 1978. Flannelmouth, white, and bluehead suckers, redside shiners, fathead
<br />minnows, and speckled dace were most commonly collected from the Yampa River. Flannel-
<br />mouth suckers, mountain whitefish, and speckled dace were most abundant in the White
<br />River. Growth of mountain whitefish and flannelmouth suckers was relatively slow after
<br />the first and third years of life, respectively. Growth of white suckers waS similar to
<br />that reported in other streams, and Colorado squawfish in the Yampa River grew faster than
<br />squawfish collected in the Green River in 1964-76. ' Mayflies were the predominant aquatic
<br />macroinvertebrates in both streams, and caddisflies and true flies were next in abundance.
<br />Data are provided on the water quality in the two rivers.

<br />
<br />Describes an aquatic inventory of the Yampa River between Lily Park Pool near Cross
<br />Mountain Canyon and Hayden, Colorado, and of the White River between Spring Creek and
<br />Rio Blanco Lake. Eighteen Colorado squawfish were collected from the two rivers dur-
<br />ing July 1975 and September 1978. The age and growth of Colorado squawfish, flan-
<br />nelmouth suckers, and mountain whitefish was determined and foods eaten by channel
<br />catfish, bluehead and flannelmouth suckers, and red shiners were summarized.
