Silver Salmon — Kenai River

Coho Silver Salmon on the Kenai: Run Timing, Tactics & Where to Find Them

Silver salmon — also called coho — are the Kenai River's late-season prize. They arrive in August and provide exceptional fishing through October, long after the sockeye crowds have gone home. Silvers are aggressive, acrobatic fighters that hit flies and lures with abandon, making them one of the most exciting species in Alaskan freshwater fishing.

2026 Coho Run Timing & Migration

Silver salmon enter the Kenai River from Cook Inlet, which means the lower river sections see the earliest fish starting in late July and early August. As the run progresses, these fish push upstream into the middle and upper river sections, with peak numbers in the upper river and tributary mouths occurring in late August and mid-to-late September.

ADF&G counts late-run salmon using sonar. Unlike sockeye salmon, which are counted at River Mile 19, silver salmon passage is assessed at the River Mile 14 ARIS Sonar station in the lower Kenai River.

Silver Salmon Limits & Regulations

Under standard Kenai River sport fishing regulations, bag limits for Silver salmon change as the season progresses to protect stocks and allow for sustainable harvest:

• July 1 – August 31: The daily bag and possession limit is 2 Silver salmon.
• September 1 – November 30: The daily bag and possession limit increases to 3 Silver salmon.

Best Techniques for Kenai Coho

Unlike sockeye, which are targeted using the Kenai flip technique, silver salmon are active predators in fresh water and will strike moving lures aggressively.

• Hardware: Spinners (Blue Fox Vibrax size 4 or 5) and spoons in silver, pink, or chartreuse are highly effective when cast into slow-moving pools and slackwater sloughs.
• Fly Fishing: Strip flies such as the Dolly Llama, Egg Loop, or pink Hare's Ear patterns. The aggressive nature of coho can result in spectacular surface strikes when they target twitching topwater patterns in the morning.
• Drift Boat Strategy: Drift boat fishing allows you to cover holding pools efficiently and reach slower waters that bank anglers cannot easily access. Coverage is key, as silvers tend to pack into specific pools.
