OAR 635-500-1160. Winter Steelhead
The following operating principles apply to the Main Stem Willamette subbasin:
(1) Escapement of late-run winter steelhead to tributary subbasins has priority over harvest in the main stem Willamette River;
(2) Increase the average annual run of indigenous, late-run (15 February–15 May) winter steelhead above Willamette Falls to levels needed to achieve desired status for independent populations in subbasins, as identified in the Upper Willamette River Conservation and Recovery Plan for Chinook Salmon and Steelhead (OAR 635-500-6600).
