U.S. seeks fish entrainment study at Washington’s Kachess Dam

The Bureau of Reclamation seeks bids from firms to conduct a fish entrainment study at Kachess Dam on the Upper Yakima River near Easton, Wash. Bids are due April 8.

Kachess Dam is a 115-foot-tall, 1,400-foot-long earthfill structure built for water storage as part of Reclamation’s Yakima Project.

Reclamation plans to begin a fish entrainment study at Kachess to increase its understanding of fish entrainment at five Yakima Project storage dams. Studies performed at 13.6-MW Tieton Dam have shown a variety of valued species including endangered bull trout are being entrained.

The agency seeks a contractor to work with Reclamation staff who are to acquire and install a rotary screw trap and split-beam hydroacoustic array. The equipment is to be operated at Kachess between May and October 2011.

The contractor is to provide field data collection and technical oversight for the sampling activities.
