Fishing Guides
A smaller river for anglers who want fewer boats around. The Kasilof flows about 17 miles from Tustumena Lake to Cook Inlet, with salmon and trout in a quieter, less crowded setting.
Tustumena Lake
The Source
of the Kasilof
The river begins at Tustumena Lake, Alaska’s eighth-largest lake and one of the largest glacier-fed lakes in the state. Inside the Kenai National Wildlife Refuge, its clear, cold, deep-blue water feeds the Kasilof with nutrient-rich conditions that support healthy salmon and trout.

• Kings entering the Kasilof run smaller than Kenai kings but still fight hard. Drift fishing the upper river is popular for kings.
• Many anglers favor the lower river for sockeye, where easy access and the tides keep fresh fish moving upriver.
• The late coho run brings big fish with fewer people on the river.

What Anglers Say
★★★★★
Neither my husband nor I had fished for salmon before and he helped us get the hang of things quickly. We ended up catching 10 sockeyes.

★★★★★
He suggested the Kasilof River rather than the Kenai River because it was less crowded. We shipped home 35 pounds of sockeye & had a great time.

Our family of 5 had an excellent adventure with Captain Mark on the Kasilof River fishing for King salmon! Captain Mark kept our spirits and energy up even during the wet weather.
