As a part of the Nebraska Game Commission’s fishery management program, a stream survey was initiated on several trout streams in northeast Nebraska during 1962. The study was designed to evaluate the streams for cold water sport fisheries and to intensify management activities. Information collected on this survey appeared to lend itself to a specific study. The east branch of Verdigre Creek was selected as the experimental stream. Here the watershed was at least partially controlled and managed by the Nebraska Game Commission. Approximately 1,400 acres of this watershed are State owned. Because no intensive data had been collected from the east branch prior to management, a control stream was necessary for comparison purposes. The middle branch of the Verdigre Creek was chosen as the control since it simulated conditions which had been present on the east branch before watershed management was intensified. The purpose of this study was to show how watershed management adjacent to a small stream affects conditions for aquatic organisms with special reference to insect populations.
