The map identifies streams where removal-fill permits are often required to help protect critical habitat for salmon species
The State of Oregon has published the 2025 essential salmonid habitat map, which shows streams where activities like building docks or adding riprap usually require a removal-fill permit.
The map identifies streams that are critical habitat for Chinook salmon, steelhead trout, and other sensitive, threatened or endangered fish species. Oregon law protects these streams by requiring a removal-fill permit for most projects that remove or add any materials. View the 2025 map and learn more.
The map is updated as often as yearly to reflect current Oregon Department of Fish and Wildlife data. These regular updates keep habitat information accurate, which in turn helps property owners do their part to protect fish, said Oregon Department of State Lands Director Vicki Walker.
“Anyone who lives along a river or stream should check the map,” Walker said. “The first step in protecting fish populations is knowing whether a waterway is essential habitat.”
The 2025 update added approximately 113 stream miles of essential habitat in multiple areas of Oregon. Approximately 12 stream miles are no longer essential habitat. See the draft map to view the changes for 2025.
The annual map update process includes Tribal engagement and a public review and comment period.
