Columbia River System Operations

Columbia River System Operations

The U.S. Army Corps of Engineers, Bureau of Reclamation, and Bonneville Power Administration, as co-lead agencies, are preparing an environmental impact statement (EIS) in accordance with the National Environmental Policy Act on the operations and configurations for 14 federal projects in the Columbia River System in the interior Columbia River Basin.

In this Columbia River System Operations EIS, the three co-lead agencies will present a range of reasonable alternatives for long-term system operations and evaluate the potential environmental and socioeconomic impacts on flood risk management, irrigation, power generation, navigation, fish and wildlife conservation, cultural resources, water quality and recreation.


On October 19, 2018, the federal co-lead agencies, NOAA Fisheries, and the U.S. Fish & Wildlife Service received a directive from the President to develop a schedule to complete the Columbia River System Operations (CRSO) Environmental Impact Statement (EIS) and associated biological opinions by 2020. We are working together to develop that schedule to submit to the Chair of the Council on Environmental Quality (CEQ) within the 60-day timeframe as required by the President.

After submitting a schedule to CEQ and once a final schedule is developed, we will provide the timeline to cooperating agencies, states, tribes, and the public. We are committed to continuing to conduct an open, transparent, and collaborative process as we implement the new schedule and complete the CRSO EIS.
