Willamette Fish Operations Plan Willamette Valley Project November 2014 Draft Report Willamette Fish Operations Plan EXECUTIVE SUMMARY The U.S. Army Corps of Engineers (USACE) constructed and operates a system of 13 dams and reservoirs, associated bank protection program, and mitigation fish hatcheries known as the Willamette Project within the Willamette River Basin of northwest Oregon. In 2008, the National Marine Fisheries Service and the U.S. Fish and Wildlife Service released their Biological Opinions on the continued operation of the Willamette Project. Reasonable and prudent alternative 4.3 calls for the development of the WFOP and specifies that the elements shown below be part of the plan. • Identify optimal operating criteria for Green Peter, Foster, Detroit, Big Cliff, Cougar, Fall Creek, Dexter, Lookout Point, and Hills Creek dams to minimize adult and juvenile fish injury and mortality to the extent possible with existing facilities and operational capabilities. • Identify protocols for optimal handling, sorting, and release conditions for ESA-listed fish collected at USACE-funded fish collection facilities, including but not limited to the Minto Fish Facility, Foster Dam Fish Facility, Fall Creek Fish Facility, Dexter Dam Fish Collection Facility, and at the Cougar Fish Facility. • Identify the number, origin, and species of fish to be released into habitat upstream of USACE dams, incorporated into the hatchery broodstock, or taken to other destinations. • Describe scheduled and representative types of unscheduled maintenance of existing infrastructure (dams, transmission lines, fish facilities, etc) that could negatively impact ESA- listed fish, and describe measures to minimize these impacts. • Describe procedures for coordinating with federal and state resources agencies in the event of scheduled and unscheduled maintenance. • Describe protocols for emergency events and deviations. The main report for the WFOP provides the overarching conditions, effects on ESA-listed fish species, and protocols/procedures for the WVP as a whole. These items are then developed in more detail in the specific operational plans prepared for each individual Willamette subbasin that are appended to this document. The WFOP will guide WVP personnel, including contractors and other agencies, responsible for carrying out fish hatchery and passage measures, and will help to ensure that fish facilities are operated using best practices and are consistent with the terms of the 2008 Biological Opinions for the WVP.
