Kasilof River Fishing Guides

We offer daily fishing trips with our amazing Kasilof River fishing guides beginning in mid-May and extending into October. We begin the season with king salmon and then pursue both sockeye and silver salmon before ending the Kasilof fishing season with steelhead trout.


Where is the Kasilof River?

The Kasilof River is located 10 miles south of Soldotna and the famous Kenai River. It has long been known as the Kenai’s little sister, but it has its own unique history and reputation and offers many excellent fishing opportunities throughout the summer.

The Kasilof River is a large glacial river that drains Tustumena Lake—the largest freshwater body on the Kenai Peninsula and the eighth largest lake in Alaska. Both the river and the lake lie entirely within the Kenai National Wildlife Refuge.

The Kasilof River begins at the outlet of Tustumena Lake and flows for 20 miles before emptying into Cook Inlet.

Kasilof River Fishing and Run Timing

Kasilof King Father Son 1000×750

The Kasilof River hosts four species of Pacific salmon: king, sockeye, silver, and pink. The season begins in mid-May with a hatchery return of king salmon to Crooked Creek, a small tributary of the Kasilof located just above tidewater.

This early run consists of both hatchery-raised and naturally produced kings, and it typically peaks from late May through the first two weeks of June. Next to arrive are the sockeye salmon, which begin showing up in late May and continue migrating through July and into August.

The peak of the sockeye run usually occurs during the first couple of weeks in July. Silver salmon start arriving in earnest by early August, with the peak fishing window running from the last week of August into the first week or ten days of September.

Pink salmon are present in August and September, with the highest numbers returning during even-numbered years. The final fish to arrive is the steelhead. They begin returning in late August and continue to run through the fall months of October and into December. These fall-run steelhead overwinter in the river and lake, completing their spawning cycle in the spring.

Our Kasilof River fishing guides know when and where to find Salmon so that your trip is the best it can be!

In addition to salmon and steelhead, the Kasilof River also supports populations of both resident and sea-run Dolly Varden char, as well as a resident population of rainbow trout.

Where Do We Fish The Kasilof River?

Where we fish on the Kasilof River depends largely on the species and the time of year.

For king salmon, we fish only one section of the river, as the Kasilof is closed to king fishing above the Sterling Highway bridge. As a result, our king salmon trips focus exclusively on the stretch from the Sterling Highway down to just above tidewater.

Sockeye salmon fishing takes place both above and below the bridge. The upper float is longer, offering more scenic views and access to a greater number of fishing spots. However, the lower stretch can be extremely productive, as tide-fresh sockeye often arrive in tight, concentrated groups.

Silver salmon can also be targeted above and below the bridge, but we prefer the water below. Silvers within tidal reach are especially aggressive and provide exciting action. For steelhead, the best fishing is between Tustumena Lake and the Sterling Highway. These elusive fish move quickly, and covering water is key to finding them.

How we fish the Kasilof River

Our Kasilof River fishing guides are experienced and passionate anglers who have spent countless hours on the river. The Kasilof River is a drift boat only fishery, which means motor use is prohibited while fishing. This makes for a very peaceful and unique angling experience. Fishing for kings and silver salmon is largely done from the drift boat with diving plugs or bouncing lures/baits on the bottom.

With sockeye salmon, we use the boat to reach strategic gravel bars and then get out of the boat and fish from shore. We do occasionally catch sockeye from the boat while targeting king salmon. For steelhead, we fish with fly rods or spinning rods with floats and drift fish, or get out and fish from shore.

FAQ’s About Kasilof River Fishing

What is the difference between the Kasilof River and the Kenai River?

The Kenai and the Kasilof Rivers are similar in many ways but also very different. The Kasilof is considerable smaller than the Kenai and much shorter in length. The Kasilof is 17 miles long from its outlet at Tustumena Lake to where is enters Cook Inlet. The Kenai, by comparison, is 83 miles long. The Kasilof has one lake in its system (Tustumena) and the Kenai has two Lakes (Kenai and Skilak). The Kasilof is largely a drift boat only river and the Kenai is mostly accessed by power boat.

Can you keep King Salmon in the Kasilof River?

The early run of Kasilof River King salmon is one of the last viable king salmon fisheries available in all southcentral Alaska. This is a hatchery origin run that returns to a tributary to the Kasilof named Crooked Creek and the fishery takes place from mid-May through mid-June. The fish average 12-18 lbs. and the limit is two fish per person, per day. The July king salmon fishery on the Kasilof river will remain closed for the foreseeable future.

Can you fish the Kasilof River without a guide?

Yes. Though your chances of a successful fishing trip are greatly increased with one of our Kasilof River fishing guides, the Kasilof has several access points for fishing from the shore, and a guide is not required on either river to fish both from a boat or from shore.

What is the best month for salmon fishing on the Kasilof River?

The best time for Kasilof River fishing all depends on the species you are targeting. Sockeye salmon fishing is best in mid to late June for Russian River bound sockeye and in July and early August for Late Run Sockeye. Silver Fishing is best in August and September. Pink salmon fishing is best in August, but they are only present in high numbers on even years.
