****UPDATE May 31, 2017****
The Walla Walla District of the U.S. Army Corps of Engineers (Corps) has now closed the public scoping period for the Lower Granite Project Master Plan (MP) revision. Planners added 30 days to the originally scheduled 30 day scoping period, which ran from March 22 to May 22.
The Corps conducted public scoping meetings March 22-23 in Clarkston and Pullman to support the MP revision and Environmental Assessment. The Corps invited comments from the public regarding management of natural resources and recreational opportunities that should be considered for the Lower Granite Master Plan. Public comments received during this process will be considered during development of the draft MP. The Corps will also prepare an Environmental Assessment (EA) to address potential effects associated with MP revision. The Corps will consider all comments received.
Public input will be sought again when the draft MP is done sometime in early 2018.  
The Master Plan is the strategic land-use management document that guides the comprehensive management and development of all recreational, natural and cultural resources on Corps-managed land associated with Lower Granite Lock and Dam, throughout the life of the water resource project.
Lower Granite’s existing 1974 MP and other associated documents are available for review on the Corps’ website http://www.nww.usace.army.mil/Locations/District-Locks-and-Dams/Lower-Granite-Master-Plan/.

A master plan is the guidance document that describes how the resources of the project will be managed in the future and provides the vision for how the project should look in the future. It’s typically updated every 20 years. The master plan does not address issues such as flood risk management (levees/dams/channels/etc.), operational areas (dam, navigation lock, fish passage facilities, power house, etc.) and water level management, which are addressed in other guidance documents.

Development of the revised master plan will include consideration of regional and ecosystem needs as well as public interests and desires.

The Lower Granite Master Plan Revision’s main objectives is to create a Master Plan that balances public use of federal lands and waters with the conservation and protection of natural resources to ensure a sustainable future for the project.


Lower Granite Master Plan was last completed in 1974, and a lot has changed since then:


•The 1974 Master Plan focused on initial recreational development and less on natural resources and fish and wildlife.

•Original land classifications do not meet current Corps regulations.

•There are new invasive and ESA-listed species to be considered in the management of project lands and waters.

While no two visitors share exactly the same vision of how the project should look in 20 years, we believe all have its best interest in mind.
