Winter Steelhead in Alaska
Alaska Department of Fish and Game names 7 steelhead rivers, from the Situk River to the Dog Salmon River, and describes spring run Mar 1 to Jun 10, fall run Aug 1 to Oct 31, spawning Apr 15 to Jun 10. 2 of them carry a live USGS gauge, and the one with a discharge record is shown against the median for today's date.
Alaska steelhead rivers, run timing and flow today
Each river below is one Alaska Department of Fish and Game names for steelhead, with the timing it gives and the sentence it came from. Beside it, the latest discharge from the river’s USGS gauge and the median discharge for today’s date across that gauge’s years of record, so a reading of 150% means the river is carrying half again its usual flow for the day. 2 of the gauges also report water temperature.
| River | Run timing | Hatchery | Flow now | Median for today | Water temp |
|---|---|---|---|---|---|
| Situk RiverYakutat (Southeast) Alaska's best known steelhead river and home of the oldest aged Alaska steelhead; ADF&G's weir counts spent adults moving back to sea each spring. ADF&G source USGS gauge 15129500 | spent fish head back downstream in May and June | Wild run | Loading | Loading | Loading |
| Anchor RiverLower Cook Inlet (Kenai Peninsula) A small fall run on the lower Kenai Peninsula; runs vary and are usually small, and fish come in from mid August into November. ADF&G source USGS gauge 15239900 | fall run, mid August through early November | Wild run | Water temperature only at this gauge | Loading | |
| Kasilof RiverCook Inlet (Kenai Peninsula) ADF&G's Kenai Peninsula run timing chart lists both a spring and a fall steelhead window here. ADF&G source | late March through mid May, and late August through mid November | Wild run | Run timing from ADF&G, with the note and source beside it. | ||
| Karluk RiverKodiak Island West Kodiak river with a weir near the mouth; ADF&G's fish counts include a steelhead series alongside the big sockeye run. ADF&G source | Spring run, Mar to Jun; Fall run, Aug to Oct | Wild run | Run timing from ADF&G, with the note and source beside it. | ||
| Ayakulik RiverKodiak Island Southwest Kodiak river whose weir counts include steelhead. ADF&G source | Spring run, Mar to Jun; Fall run, Aug to Oct | Wild run | Run timing from ADF&G, with the note and source beside it. | ||
| Buskin RiverKodiak Island Road system river near the city of Kodiak; the lower weir that counts coho through September also logs steelhead. ADF&G source | Fall run, Aug to Oct | Wild run | Run timing from ADF&G, with the note and source beside it. | ||
| Dog Salmon RiverKodiak Island South Kodiak river draining toward Olga Bay; its weir counts include steelhead. ADF&G source | Fall run, Aug to Oct | Wild run | Run timing from ADF&G, with the note and source beside it. | ||
When steelhead are in Alaska rivers
The months ADF&G gives for each river, laid on a July to June year so a winter run reads as one bar. Rain and water temperature move the weeks inside those months from one year to the next.

The runs, in ADF&G’s words
- Spring run, Mar 1 to Jun 10. Most Alaska steelhead come back in spring, March to early June, and spawn within weeks.
Spring-run steelhead return to streams in Alaska between March and early June while the rare summer-run fish will return to freshwater during July.
Source - Fall run, Aug 1 to Oct 31. Fall fish enter August through October, possibly later, and hold through winter to spawn the next spring.
Fall-run steelhead enter the freshwater systems as adults in August through October and possibly throughout the winter.
Source - Spawning, Apr 15 to Jun 10. Whatever month they return, all Alaska steelhead spawn in spring once streams warm to about 6 to 9 C.
Regardless of when they return to freshwater, all steelhead spawn during the spring months when daily water temperatures reach 6 – 9° C, usually about mid-April through May to early June.
Source
Winter-run Steelhead return from the ocean at age 4 or 5 years, and travel to their spawning grounds from November to April.

- Situk River steelhead weir (Fish Counts, location 5)ADF&G, weir count, daily
The Situk River weir crew counts post-spawning downstream migrations of adult Steelhead beginning in spring (May-June) each year, and upstream pre-spawn salmon migrations beginning in summer (June-August).
