Master plans improve natural resource management planning strategies and ensure adherence to federal regulations and national goals in a comprehensive and consolidated manner.
Portland District updated the mid-Columbia and the Rogue River basin master plans in 2019-2020. This included an integrated environmental assessment, prepared in accordance with the National Environmental Policy Act.
These two regional master plans updated outdated individual project master plans that date back to the mid-1970s. The master plans and integrated environmental assessments address elements such as hydrology, fish and wildlife resources, ecological setting, cultural resources, and recreation facilities, among many other things. Outdated land classifications, sustainable natural resource management, boundary encroachments, aquatic and terrestrial invasive species management, and federal and state listed threatened and endangered species are also addressed. Updated master plans incorporate public comments and improve natural resource management planning strategies for the next 20 years.
