Steelhead in Alaska

Oncorhynchus mykiss[1]

35 Alaska waters whose agency species list names steelhead. Each links to its water page (gauge, regulations, access map, guides and shops) and to the agency list it comes from.

Alaska waters

Most fished first. A species missing from an agency list does not mean it is absent; this page lists only waters whose list names it (at least 5 are needed for a page).

Identification

  • Adult steelhead back from one to three years at sea are usually heavily marked with irregular dark spots, both above and below the lateral line.[2]
    What the source says
    “Adult steelhead which have spent 1 to 3 years in the ocean are generally heavily spotted with irregularly shaped dark spots both above and below the lateral line.”
  • Fresh from the ocean, steelhead can look much brighter and more silver than resident rainbow trout.[2]
    What the source says
    “Steelhead fresh from the ocean can be very bright and much more silver in color than resident rainbow.”
  • Washington describes steelhead as having dark spots over the whole fish, tail included, with slight to strong rainbow colouring.[3]
    What the source says
    “Steelhead also have dark spots scattered over the entire fish, including the tail, with slight to pronounced rainbow coloring.”

Status, protections and rules

As each agency stated them on the date read; a rule applies only where its agency says so. Check the current regulations for the water before you fish.

  • Under the US Endangered Species Act, NOAA Fisheries lists one steelhead DPS as endangered and 10 DPSs plus one experimental population as threatened.[1]
    What the source says
    “Under the Endangered Species Act, one distinct population segment (DPS) is listed as endangered, while 10 DPSs and one experimental non-essential population are listed as threatened.”
  • NOAA's threatened steelhead units are California Central Valley, Central California Coast, Lower Columbia River, Middle Columbia River, Northern California, Puget Sound, Snake River Basin, South-Central California Coast, Upper Columbia River and Upper Willamette River; Southern California is endangered.[1]
    What the source says
    “ESA Endangered Southern California DPS ESA Threatened California Central Valley DPS Central California Coast DPS Lower Columbia River DPS Middle Columbia River Northern California DPS Puget Sound DPS Snake River Basin DPS South-Central California Coast DPS Upper Columbia River DPS Upper Willamette River DPS”
  • Oregon's March 2024 notice for the Santiam River said anglers cannot keep wild winter steelhead but may keep hatchery steelhead, which have the adipose fin removed; wild fish have it intact. Rules vary by river and year, so check current regulations.[4]
    What the source says
    “While anglers cannot keep wild winter steelhead, they can still fish for and retain hatchery steelhead or hatchery spring Chinook. The peak run timing for these fish in the Santiam basin is usually in May and June, though some early fish do arrive in April. Hatchery summer steelhead have their adipose fin removed while wild steelhead have theirs intact.”

Water temperature in Alaska

Alaska Department of Fish and Game publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Alaska rule:

  • Under the federal 68°F lineThat is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
  • Stressful for troutAt 68°F the U.S. Fish and Wildlife Service says rainbow trout “start stressing”, and the National Park Service at Grand Teton recommends that anglers “cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F.” Its advice: “Fish early in the morning while the water temperature is cooler”, “Play and land fish quickly to reduce exhaustion stress” and “Keep the fish in the water as much as possible.”
