U.S. extends call for fish passage design for Washington’s Mud Mountain Dam

The U.S. Army Corps of Engineers has extended the deadline for expressions of interest from firms to develop plans and specifications for construction of fish passage at the Corps’ Mud Mountain Dam, a flood control structure on Washington’s White River. Responses now are due March 10.

The Corps’ Seattle District previously called for responses by Feb. 17.

Mud Mountain was completed in 1948 to protect the lower White and Puyallup valleys by holding back water from heavy rains and snow melt then releasing it slowly into the river. Between flood events, the reservoir is usually empty except for normal flows of the White River.

Fish passage is to be constructed at Mud Mountain Dam in accordance with a 2014 biological opinion issued by the National Marine Fisheries Service that expressed concern about effects of the project’s operations on species listed under the Endangered Species Act.

The Seattle District seeks architect-engineering services to develop plans and specifications ready for advertising a construction contract valued at $50 million to $100 million in about 18 months. Fish passage designs must include 95 percent fish attraction into the facility and 98 percent survival through the facility to release.

A pre-solicitation notice may be obtained from the Federal Business Opportunities Internet site, www.fbo.gov, by entering Solicitation No. W912DW15R0013 in the “Keyword/Solicitation #” box. Interested firms now are invited to submit Standard Form 330 packages to the address below by March 10. Forms may be obtained on the Internet at www.gsa.gov/portal/forms/type/TOP/category/22457/hostUri/portal.
