The U.S. Government entered into two memorandums of understanding (MOU) with various parties to stay litigation, both of which happened in 2023.
One MOU is with the Confederated Tribes of the Colville Reservation, Spokane Tribe of Indians, and the Coeur d’Alene Tribe to support the implementation of the Upper Columbia United Tribes’ (UCUT) Phase 2 Implementation Plan (P2IP) for testing the feasibility of reintroduction of salmon in the Upper Columbia River Basin over a period of 20 years. This resulted in a 20-year stay in litigation.
The second MOU is with Oregon, Washington, the Nez Perce Tribe, Confederated Tribes and Bands of the Yakama Nation, the Confederated Tribes of the Warm Springs Reservation of Oregon, the Confederated Tribes of the Umatilla Indian Reservation, and the National Wildlife Federation plaintiffs that is intended to pause the Columbia River System (CRS) litigation for up to 10 years. We refer to this MOU and the commitments made by the U.S. Government as the Resilient Columbia Basin Agreement (RCBA). Here are several things it does:
- It shifts the focus away from litigation and the uncertainty that litigation brings and allows for additional focus on planning and completing projects.
- Enables the U.S. Army Corps of Engineers (USACE) to leverage regional partnerships to expand its contributions to improvements in conditions for salmon and other native fish in the CRS which are a vital resource for the people of the Pacific Northwest.
- Provides an opportunity to make improvements to system infrastructure and address maintenance backlogs.
- Leverages the programs and resources of multiple federal agencies to accomplish shared goals in collaboration with regional sovereigns.
Our Commitments:
As part of the MOUs with Tribes, States, and other parties, the U.S. Government developed a package of actions and commitments that it believes will provide meaningful improvements for native fish in the basin while still providing affordable and reliable clean energy, supporting the local economies of communities that rely on the CRS, and meeting the many resilience needs of the region.
It is important to note that USACE’s commitments do not call for breaching dams, nor does USACE have authority to take that action. Breaching the lower Snake River dams would require authorization and appropriations from Congress.

USACE commitments include:
- Expanded spill operations to support juvenile salmonids, while maintaining our ability to continue to meet other authorized purposes of the system and with appropriate monitoring and studies to avoid impacts to adult salmonids and other native fish.
- Seeking increased funding to address the Operations and Maintenance backlog as well as improvement of fish-related infrastructure on the system.
- Expanded portfolio of ecosystem restoration studies and projects under existing authorities, including Cold Water Refuge projects.
- Studies to further transportation and recreation analyses related to the lower Snake River projects. Learn more by reading this news release.
- Recreation study: State and federal officials estimate the recreation study will cost $1.2 million and expect to complete it by 2026. The recreation study will seek to identify the potential loss of existing recreation opportunities associated with the draw down of reservoirs on the lower Snake River as well as necessary investments to accommodate potential future recreation opportunities under a dam breach scenario.
- Transportation study: The transportation study will add $750,000 to an existing $4,000,000 Washington State study and expand the limits of the study into Idaho and Oregon. Officials expect to complete it in late 2026. The transportation study will analyze future transportation needs, volume estimates of goods to be transported, and evaluate changes in infrastructure that would be necessary to shift away from river-based transportation methods.
- Review of existing environmental compliance documents to determine whether additional compliance is necessary.
USACE will continue engaging with our regional Tribes, partners, stakeholders and the public as we undertake this important work. We recognize we have an important job to do, and we will continue meeting all authorized project purposes at the dams in the Columbia River System as we implement these agreements.
