Kasilof River
Steelhead Fishing Trips
Our Kasilof River steelhead fishing trips begin in early September and run through the month of November. We offer both full and half day charters and prefer to keep these trips to two anglers per boat, three max. Fly fishing is the preferred method although spinning tackle is available as well.
Steelhead fishing on the Kasilof River is entirely catch and release and the use of bait is strictly prohibited.
Fish With Experienced Kasilof River Steelhead Guides
The Kasilof River does receive a favorable run of fall Steelhead annually. These anadromous rainbows start arriving in mid to late August and return in the highest numbers from September until November.
Use of a boat and covering a lot of water is essential in this fishery as the Kasilof is a large river in the fall and fish can be spread out in select concentrations throughout the system.
As with all steelhead fisheries, the Kasilof steelhead require patience and refined technique to be successful, but the fish are fresh from the ocean and fight very well in the glacial fed water of the Kasilof.
We primarily target these fish with fly rods, both single hand and spey, but spin tackle is available if preferred.
Kasilof River Steelhead Fishing Techniques:
Kasilof steelhead time their fall migration to take advantage of the silver salmon spawn and often feed on loose salmon eggs. Single egg patterns or beads are very effective and we most commonly dead drift those using a fly rod and a strike indicator or with a spinning rod under a float. Kasilof steelhead will also aggressively attack swung flies such as intruder patterns presented from both single hand and spey rods.

Kasilof Steelhead Run Timing:
September/October/November:
We begin to see the first Kasiof steelhead while fishing for silver salmon in August and early September. By mid to late September the silver run decreases significantly and the number of newly arriving Kasilof Steelhead increases considerably.
Peak timing for this return normally occurs in the month of October although fresh fish continue entering the river into the month of November. As with all steelhead fishing, anglers should prepare for rainy and cold weather.
Things To Know About Kasilof River Steelhead:
*Spawning Season & Conditions: Spawning begins in early spring as water temperatures rise (daily temperatures around 42–46°f).
*Habitat: Maturing adults seek out shallow gravel riffles or clear streams suitable for nesting.
*Nest Preparation: The female uses her tail to dig a redd (nest) about 4–12 inches deep and 10–15 inches wide.
*Egg Numbers: Between 200 and 8,000 eggs can be deposited in a redd. The eggs are fertilized by the male’s milt and then covered with gravel.
*Hatching & Emergence: Hatching occurs anywhere from a few weeks to four months after spawning (depending on water temperature), with fry emerging a few weeks later after absorbing their yolk sacs.
*Age, Growth, and Maturity: Genetics, food availability, water temperature, population density, and habitat productivity all influence growth and the onset of sexual maturity. Steelhead generally spend about 3 years in freshwater before migrating to the ocean, followed by an additional 2 years at sea before returning to spawn. Steelhead exhibit significant variability; some return after just one year at sea, while others may spend up to 4 years.
*Return Periods: Kasilof Steelhead are considered Fall-run: they enter freshwater from August through October (and sometimes even through winter), though spawning still occurs in the spring when temperatures are optimal.
*Early Life: Upon emerging, the fry form schools along stream margins or sheltered lake shores. Initially, they feed on small crustaceans, plant material, and various aquatic insects (and their larvae).
*Freshwater to Ocean Transition: Juvenile steelhead begin their migration (smolting) to saltwater from late April through mid-June.
*Ocean Phase: Once in the ocean, steelhead grow quickly due to plentiful food sources. They can travel hundreds of miles into open waters before returning to their natal streams. Detailed patterns of ocean migration remain less well-documented.
