Corps Seeks Comment On Draft Mid-Columbia River Regional Master Plan & Environmental Assessment

Published Sept. 21, 2018
PORTLAND, Ore. – The U.S. Army Corps of Engineers, Portland District (Corps) is making the 60 percent draft Mid-Columbia River Regional Master Plan and Integrated Environmental Assessment (EA) available for public review. 

Master plans for the mid-Columbia River projects date back to the 1970s.  A regional master plan is needed to integrate and update management and development planning for the mid-Columbia River projects in order to guide responsible stewardship and sustainability of project resources for the benefit of present and future generations. 

The purpose of the Mid-Columbia River Regional Master Plan is to serve as the overall strategic management document guiding the Corps’ comprehensive administration and development of recreational, natural and cultural resources on Corps-owned lands associated with projects at Bonneville Lock & Dam, The Dalles Lock & Dam, John Day Lock & Dam and Willow Creek Dam. The master plan would provide an overall land use management plan, including objectives and concepts for the efficient and cost-effective management, development and use of project lands for the next twenty years. 

Integrated into the master plan is an EA, prepared in accordance with the National Environmental Policy Act (NEPA). The master plan and integrated EA include land classifications, resource objectives and plans and natural resource management. Resources evaluated include cultural resources, fish and wildlife, aquatic and terrestrial invasive species management, threatened and endangered species, ecological settings, and recreation use and facilities on Corps lands within the master plan boundaries. Environmental impacts from a no-action alternative and a proposed-action alternative (implementation of the master plan) are evaluated in the integrated EA.

Public Comment Period: The 60 percent draft master plan and integrated EA will be available for public comment for 30-days after the date of this public notice. This public comment period is intended to provide those interested in or affected by this action an opportunity to make their concerns or comments known. The Corps will consider comments received during the 30-day comment period in the development of the 90 percent draft master plan. The 90 percent draft master plan will also be provided for public review.

The draft master plan and integrated EA are available for download at the following link:

All interested parties are invited to attend the public meeting in Dallesport, WA: 

Date: October 9, 2018, from 5:00 PM to 7:00 PM
Location: Dallesport Community Center
136 6th Ave

Each Mid-Columbia River dam contributes to a water resource management system that provides flood risk management, power generation, water quality improvement, irrigation, fish and wildlife habitat and recreation on the Columbia River and some of its tributaries.

Federal, state and local agencies, and many Mid-Columbia River Basin stakeholders are united in their commitment to protect native fish and their habitat. These entities have been working together for many years on improvements essential for the successful protection and recovery of these fish populations.
