The Kasilof River is located 12 miles south of the Kenai River and the town of Soldotna. It originates from Tustamena Lake, the largest Lake on the Kenai Peninsula and flows 17 miles before emptying into Cook Inlet. The Kasilof is much more glacially turbid than the Kenai and is fished exclusively via drift boat. The lower Kasilof is the most heavily fished section of the river with two primary returns of king salmon. The first run is largely hatchery in origin with most of the fish returning to a tributary just above tide water named Crooked Creek. This fishery begins in mid-May and extends through the month of June. The late run of Kasilof Kings arrived in early July and peaks in the third and fourth week of the same month before closing on August 1. This return is entirely wild fish that are primarily headed upriver below Tustamena Lake to spawn. The late run Kasilof kings, known as “Tusties,” rival the large Kenai Kings in size with fish over 50 lbs. not uncommon. The Kasilof also sees a very large return of sockeye salmon that begins in late May and peaks in early July. In August and September, the Kasilof sees a good return of silver salmon as well as a steelhead run in late September, October and November.
