Abstract
A method and system allowing fish to migrate upstream and downstream, bypassing dams, obstructions, either man-made or natural, safely, freely and in a natural manner. The system consists of a meandering 'nature-like' channel constructed of pneumatically placed concrete, shotcrete or gunite that simulates a waterway bed condition. The construction of riffles, ledges, undercut banks and other natural-like features to provide a foundation for the placement of fish habitat, such as gravel beds, boulders, logs, and the like. The placement of sand, gravel, cobbles and such to create and provide an aquatic environment to sustain plant and aquatic life. The introduction of plants and other aquatic life to provide forage, cover and a year around natural-like environment within a river or stream-like migratory bypass channel.
