This site shows what fish are migrating through the ladder at Bonneville Dam's Oregon Shore counting station.
Follow this link to see a short video of the fall salmon run at its peak: Fall Salmon Run

About the image: The lines you see are used by the fish counter to determine if a fish is a jack.

• The distance between the left line and right line is 22 inches.
  Chinook jacks are smaller than 22 inches.
• The distance from the middle line to the right line is 18 inches.
  Coho jacks are smaller than 18 inches.

On July 11, 2008, the U.S. Fish and Wildlife Service and NOAA Fisheries issued biological opinions to complete consultations with the U.S. Army Corps of Engineers, the Bonneville Power Administration and the Bureau of Reclamation on the impact of the Willamette Project on ESA-listed species in the Willamette River Basin.

The Endangered Species Act requires any federal agency proposing to do anything that might affect an ESA-listed species to first seek the opinion of USFWS or NMFS about the effects of the action on the species. These resource agencies issue biological opinions to the agencies making the proposal. The goal of a biological opinion is ensuring that the proposed federal action won't reduce the likelihood of survival and recovery of the listed endangered species.

Upper Willamette River Chinook Salmon
The UWR Chinook salmon ESU includes all naturally spawned populations of spring-run Chinook salmon in the Clackamas River and in the Willamette River and its tributaries above Willamette Falls, Oregon, as well as UWR Chinook from seven artificial propagation programs (hatcheries).

UWR Chinook salmon are one of the most genetically distinct groups of Chinook salmon in the Columbia River Basin. Historically (before the laddering of Willamette Falls), passage by returning adult salmonids over Willamette Falls was possible only during the winter and spring high-flow periods. The early run timing of Willamette River spring-run Chinook salmon relative to other lower Columbia River spring-run populations is viewed as an adaptation to flow conditions at the falls.

Upper Willamette River Steelhead
The UWR steelhead distinct population segment (DPS) includes all naturally spawned anadromous winter-run steelhead populations in the Willamette River, Oregon, and its tributaries upstream from Willamette Falls to the Calapooia River (inclusive).
Winter-run steelhead enter the Willamette River beginning in January and February but do not ascend to their spawning areas until late March or April. Spawning takes place from April to early June. 

Steelhead trout (Oncorhynchus mykiss) belong to the family Salmonidae which includes all salmon, trout, and chars. Steelhead are similar to some Pacific salmon in their life cycle and ecological requirements. They are born in fresh water streams, where they spend their first 1-3 years of life. They then emigrate to the ocean where most of their growth occurs. After spending between one to four growing seasons in the ocean, steelhead return to their native fresh water stream to spawn. Unlike Pacific salmon, steelhead do not necessarily die after spawning and are able to spawn more than once. (From: http://ecos.fws.gov/speciesProfile/profile/speciesProfile.action?spcode=E08D)

The Willamette Action Team for Ecosystem Restoration will provide a forum for coordination and recommendations among the sovereign governments (federal/state/tribal) working to implement strategies for Endangered Species Act (ESA) compliance associated with the Willamette Project, which consists of 13 federal dams operated and maintained by the U.S. Army Corps of Engineers, Portland District (USACE) in the Willamette River Basin (Willamette Project), 42 miles of revetments, and the hatchery mitigation program.  Establishment of this organization is a core feature of the adaptive management strategy in the Reasonable and Prudent Alternative (RPA) developed during consultation on the Willamette Project.

The 2008 Willamette Project Biological Opinions and RPA identified numerous actions to reduce and minimize the effects of continued operation and maintenance of the Willamette Project on species listed and critical habitat designated under the ESA.  WATER's responsibilities are directed at making recommendations to the Federal Action Agencies (Action Agencies, consisting of USACE, Bonneville Power Administration, and Bureau of Reclamation) in implementing certain measures in the RPA and the Willamette BiOps.  General topics to be addressed by WATER include flow management, water quality and temperature control below dams; fish passage; hatchery management; habitat restoration; environmental coordination for construction projects; and research, monitoring and evaluation of proposed actions. 

The Willamette BiOps and RPA also include the Configurations Operations Plan (COP), which is a study mechanism the USACE will use to evaluate a range of potentially beneficial actions for listed species, some of which are prescribed as specific RPA measures with deadlines.  The WATER, and its various technical teams, will be integral to guiding research, reviewing information, and making recommendations regarding the biological benefits associated with actions evaluated within the COP. 

WATER will also serve as a forum to integrate the Willamette BiOps and RPA implementation with development and implementation of Recovery Plans associated with ESA-listed species addressed in the Willamette BiOps.  The extent of this involvement will evolve as actions are identified within the COP and as Recovery Plans are completed. 

WATER will serve as a recommendation-making body only; the Action Agencies retain responsibility for the continued operation and maintenance of the Willamette Project to meet authorized purposes and to ensure compliance with the actions described in the Willamette BiOps and RPA.  If the Services disagree with an Action Agency's decision, they may elevate the issue, if appropriate.  Although the Action Agencies retain decision-making authority with respect to implementing and ensuring compliance with the Willamette BiOps and RPA, the WATER process and structure does not take away existing authorities of other Federal and State agencies and Tribes.
WATER guidelines & procedures

Technical teams oversee implementation of the Willamette BiOps and RPA and related resource management activities. The technical teams are the level at which much of the detailed work of implementing Willamette BiOps and RPA activities are staffed, planned, scoped, designed, and implemented.  The composition of the teams reflect the scope of each team's areas of responsibility.

Functions and Requirements

The Fish Passage and Hatchery Management technical team will:

• Assist the USACE in addressing issues related to fish passage at USACE dams, including development and evaluation of fish passage designs and construction, operation, and modification of fish passage features.
• Ensure operation of USACE-funded hatcheries minimizes impacts to, and supports recovery of, ESA-listed species while maintaining hatchery mitigation requirements.
• Coordinate efforts to evaluate the feasibility of reintroduction in areas upstream of the dams.
• Assist the USACE in annually developing and updating the Willamette Fish Operation Plan (FOP).
• Evaluate the results of fish passage and hatchery-related RM&E efforts (and refine RM&E efforts accordingly).
• Develop a thorough implementation plan for the research and monitoring program that specifies which RM&E tasks related to fish passage and hatchery management will be funded and/or carried out by the State of Oregon, the Action Agencies, or other entities.
• Develop criteria for prioritizing water temperature control (WTC) proposals. (This issue may also be appropriate to be addressed in the Flow Management group).

Flow Management Technical Team

• Develop the annual Willamette Conservation Plan.
• Review and evaluate reservoir operating criteria, including mainstem and tributary flow targets and revise operating manuals where appropriate.
• Design and implement flow monitoring and evaluation studies needed to determine the effects of reservoir operations on downstream habitat conditions, aquatic species, and water quality conditions.
• Develop the annual operating plan for the conservation storage and release season.
  Make recommendations to inform USACE determination on availability of water for irrigation contracts.
• Review status of USBR's water marketing program.
• Provide advice and coordination during real-time operations, particularly, but not limited to, the conservation storage and release season.
• Conduct annual reviews of Willamette Project operations and document issues, concerns, and opportunities associated with improving operations to better meet ESA compliance requirements where possible.
• Ensure integration of water quality improvement actions undertaken by the Action Agencies to address the needs of ESA-listed species.

The Habitat Technical Team will accomplish the following tasks:

• Review and synthesize regional habitat restoration plans, habitat assessments, recovery plans, biological opinions, limiting factor information, and other available information to support the development of a Willamette Basin habitat restoration strategy.
• Identify potential restoration opportunities and opportunities to leverage different sources of habitat restoration funding.
• Assess progress towards the various habitat reasonable and prudent alternatives and compile information for reporting as needed.
• Establish criteria for implementation and compliance monitoring.
  Update restoration strategy to reflect new information including accomplishments, lessons learned, and relevant RM&E.

Research, Monitoring & Evaluation Oversight Technical Team

• Develop a basin-wide, long term RM&E plan to implement and refine the actions associated with the Willamette BiOps and RPA.
• Coordinate RM&E strategies, actions, and priorities among the Technical Teams and identify and implement RM&E activities not being accomplished by one of the Technical Teams.
• Convey RM&E priorities developed by the Technical Teams to the Steering Team and information needs from the Steering Team to the Technical Teams.
• Develop guiding principles, based on the Willamette BiOps, RPA, and other relevant documents, for basin-wide RM&E priorities, including ability to detect large-scale habitat and water quality changes resulting from the cumulative RPA improvements in these elements.
• Prioritize RM&E efforts within and among the subbasins, ensuring that efforts contribute to development and refinement of estimates for viable salmonid population (VSP) parameters, and the ability to detect their change.
• Ensure RM&E efforts support development of the COP.
• Coordinate with other basin-wide RM&E efforts, such as those associated with ESA recovery planning and implementation of other actions with biological opinions.
• Coordinate activities and priorities with other regional research programs, i.e., work being done by entities not involved with implementation of the Willamette BiOps and RPA.

Draft Charter

Draft Strategic Plan

Draft Selection Criteria

The steering team is the second tier of WATER, comprised of senior project and program managers representing the federal agencies responsible for the ESA Section 7 consultation for the Willamette Project, as well as other key federal and state agencies, and Tribes with natural resource management responsibilities critical to implementation of ESA measures. The Steering Team is responsible for overseeing and coordinating the activities of the technical teams engaged in implementation of the Willamette BiOps and RPA. It is also the level at which the participating entities will seek to resolve disagreements.
