I seen that the limit below Orofino bridge 1 fish a day 28 inches or less. Does that size limit apply to the upper Clearwater and the south fork?
Steelhead are defined as "rainbow trout that are over 20" in length." Only hatchery produced steelhead (missing adipose fin) can be harvested during an open season. If they are over 20", missing their adipose fin, with an open season, and you want to harvest the fish; then it must be recorded on your steelhead permit.
There are no specific size limits on steelhead above the Orofino Bridge.
