What Is A Steelhead?
Steelhead are rainbow trout longer than 20 inches in length in the Snake River drainage below Hells Canyon Dam, the Salmon River drainage (excluding lakes and the Pahsimeroi and Lemhi rivers), and the Clearwater River drainage (excluding that portion above Dworshak Dam and lakes). Rainbow trout longer than 20 inches in length with the adipose fin clipped (as evidenced by a healed scar) are defined as steelhead in the Snake River from Hells Canyon Dam upstream to Oxbow Dam, and in the Boise River from its mouth upstream to Barber Dam, and in the Payette River from its mouth upstream to Black Canyon Dam, during steelhead seasons.
Only steelhead with a clipped adipose fin (as evidenced by a healed scar) may be kept. These are steelhead produced in fish hatcheries which have had their adipose fin removed as juveniles. All steelhead with a non-clipped adipose fin must be released immediately to preserve the remaining wild steelhead and because wild steelhead are listed as Threatened under the Endangered Species Act. Some hatchery steelhead are not clipped as part of a program to develop additional runs of natural spawing fish. These steelhead must also be released immediately.

Anyone, except those expressly exempt, must have a valid fishing license and steelhead permit to fish for, reduce to possession, or catch-and-release steelhead. No steelhead permit is valid unless it has been properly sealed in the permit portion of the tag/permit pouch.
Any person who does not qualify as a resident must purchase either a nonresident season fishing license and a full-season steelhead permit or a nonresident 3-day salmon/steelhead license/permit.
In order to qualify for resident status, a person must be domiciled in the state for at least six months. See page 6.
Children (including nonresident children) under the age of 14 are exempt from purchasing steelhead permits. They may fish without permits if they are accompanied by a valid permit holder, provided that any fish caught must be recorded on the permit holder’s card and counted in the permit holder’s legal bag, possession and season limit. A resident child under 14 may purchase a permit without a license so that he or she may catch his or her own limit of steelhead.
When excess hatchery steelhead become available at fish hatcheries or trap facilities, they may be released in the Snake River between Hells Canyon and Oxbow dams, and in the Payette or Boise rivers to provide additional fishing opportunity. A steelhead permit is required when fishing for hatchery steelhead stocked by IDFG in these waters.
Methods of Take
• No person shall kill or retain in possession any steelhead which has been hooked other than in the mouth or jaw. Any steelhead hooked other than in the mouth or jaw must be released unharmed. See snagging definition on page 11.
• Steelhead may be taken

PLEASE NOTE
• Steelhead caught in a legal manner must be either released or killed immediately after landing.

STEELHEAD HARVEST SURVEY
Steelhead harvest and angler participation are estimated by a telephone survey conducted within a few weeks after the season closes. You may be called and asked about your effort and success.
Please save your permit until three months after the season has closed or until you are contacted by IDFG.
Steelhead Rules
PERMIT VALIDATION
When a steelhead has been hooked, landed, and reduced to possession, the angler hooking the fish must immediately:
1. Completely remove one numbered notch (*) from the permit;
2. Look up the number code from the River Location Code List and write it in the space provided; and
3. Enter the month and day the fish was caught.
However, when a steelhead is released unharmed, as in no-harvest fishing, the angler is not required to make an entry on the permit.
For example, a fish caught from the

not fish from the shoreline, including wading, and may not fish in sloughs or
tributaries on the Oregon or Washington side. An
