Anglers may now keep Ringold Hatchery steelhead that have a hole punched in the tail fin.
The revised state rule covers the area that stretches from the blue bridge on the Columbia River to the old Hanford town site wooden power line towers.
Steelhead are sedated in a chemical anesthetic, MS-222, during sampling at Priest Rapids Dam and should not be eaten for 21 days after sedation. Sedated fish are marked with a hole punch to alert anglers.
Sampling at Priest Rapids Dam has ended for the year and the last Ringold steelhead were sedated at least 21 days ago, according to the state Department of Fish and Wildlife.
Upper Columbia River hatchery steelhead with an adipose fin clip still must be released. Ringold steelhead that can be retained under fishing regulations that extend through Dec. 31 have a double fin clip.
