Working with Trout Unlimited, QCI has developed a plan to provide whitefish passage at an existing concrete irrigation diversion structure on the Big Lost River near Mackay, Idaho. The existing structure created an approximately six-foot vertical barrier to upstream fish passage. The project design utilizes a natural rock ramp/fishway incorporated into the existing diversion structure, allowing the structure to be retained.
