<br />
<br />The macroinvertebrate communities of Piceance Creek, Colorado, and its tributaries were
<br />sampled prior to exten~ive oil shale processing in the area. The fauna of upstream areas
<br />of Piceance Creek and its tributaries was composed primarily of winter species (those that
<br />complete their life cycle from fall to spring) whereas the fauna of downstream reaches of
<br />Piceance Creek was composed almost entirely of summer species. The concentration of
<br />sodium, sulfate, chloride, and total dissolved solids increased greatly in the downstream
<br />direction. The range of temperature, turbidity, severity of winter ice conditions, and
<br />effects of grazing and irrigation activities also increased downstream.

<br />
<br />Because of constraints being placed on our natural resources, it is essential for
<br />federal and state conservation agencies to cooperate on common plans for fish and wildlife
<br />management.
