Big R Super·Cor® arch allows fish to reach spawning areas in Cowlitz County, Washington

March 1st, 2004

The Super·Cor® arch, supplied by Big R Manufacturing, replaces a two-barrel concrete box structure that was causing a barrier to fish. The 32-foot arch sits on concrete footings above the natural stream bed, allowing fish to reach spawning areas upstream. The project was designed for Cowlitz County by the firm of David Evans and Associates, Inc. of Portland, Oregon and installed on the Monahan Creek Fish Passage Enhancement Project.
