Impact of Stream Relocation on Fish Populations and Bottom Fauna

摘要

Two long culverts -- much longer than culverts normally are -- were constructed as part of a highway project which necessitated relocation of portions of Bull Creek. The design of the culverts and stream relocation included new techniques of stream modification such as minimal straight channels, bank stabilization, installing instream cover for fishes and streamside plantings. This study was designed to evaluate the impact of road construction and stream relocation on stream chemistry and biota. Special consideration was given to the question of whether culverts act as barriers to fish movement.
