Yellowstone National Park Report
A study of benthic macroinvertebrate communities above and below a natural barrier to fish movement (6 m high) on Raven Creek, a tributary of Pelican Creek in the Yellowstone Lake watershed, was undertaken in July, 1977. This project is part of a U.S. Fish and Wildlife Service ecological evaluation of stream sections with and without native (cutthroat) trout populations. In July 1978 a similar study was undertaken on sections of Virginia Creek with and without introduced (brook) trout populations. A final progress report will be completed by June 30, 1979.
