The Kenai Peninsula, Alaska’s premier fishing destination, is popular due to its proximity to Anchorage, a major tourist entry point. Its reputation is enhanced by the excellent fishing in Seward, Homer, Soldotna, and Whittier. The region, known as “Alaska’s Playground,” is further celebrated for its remarkable salmon migrations in the Kenai, Kasilof, and Russian Rivers, attracting numerous visitors throughout the summer.

To sustainably manage Kenai Peninsula’s fisheries, all major rivers and salmon migrations are closely monitored using various counting techniques. The goal is to achieve accurate counts, advancing towards precise science despite challenges. This critical data is instrumental in managing fisheries, shaping regulations, and guiding sport fishermen to identify the best fishing times.

5 Primary Salmon Runs

There are five primary salmon runs on the Kenai Peninsula. Each salmon run is under close surveillance with the aid of underwater sonar technology. This is how the Kenai River fish counts are generated. This vigilant monitoring ensures sustainable fishing practices and enriches the angling experience for everyone visiting this remarkable region. Those five primary salmon stocks are:

Kenai River King Salmon – Early Run (May 15 – June 30)
Kenai River King Salmon – Late Run (July 1 – August 20)
Russian River Sockeye Salmon – Early Run (June 5 – July 14)
Russian River Sockeye Salmon – Late Run (July 15 – September 8)
Kasilof River Sockeye Salmon (June 15 – August 20)

These rivers, and the salmon that migrate up them, are concentrated in a very small area of the Kenai Peninsula. The chart shows how the sonar fish counts stack up across the summer.

Over the years Alaska has become an incredible destination for summer for families and anglers all over the world. Even those that would normally not have much of an interest in fishing cannot resist the temptation to cast a few lines. And with good reason. In the middle of these incredible salmon migrations fishing is not so much “fishing” as it is “catching.”

Those serious about angling will always ask the question, “but, when is the absolute best time to come fishing in Alaska?” The answer will be found in by looking at the fish counts.

When is the best time to come fishing in Alaska? The absolute best time to come fishing in Alaska is from July 18 to August 18. The reason for this is simple, it’s when 4 major rivers, all within just a few minutes drive of each other, experience the biggest salmon runs they’ll experience all year. And, they all do it at the same time.

Run Timing Is Critical

Salmon start flowing into these rivers as early as the middle of May and will continue all the way until October. But while one salmon run is starting, many others have not started yet. When one starts to dwindle another nearby starts up. However, for a brief 4 week window from July 18 to August 18, The Kenai River king salmon run experiences its peak, the Kenai River sockeye run experiences its peak, the Russian River sockeye late-run is in its peak, and finally the Kasilof River sockeye run is in it’s peak. There is no other time where such a confluence of fish takes place. This massive migration of salmon brings with it salmon, rockfish, whales, and countless wildlife opportunities across the peninsula.

But beware, these dates are not secret any longer and from mid-July to mid-August everything for a family vacation becomes scarce. Airline seats, rental cars, lodging, halibut charters, river charters and more all fill to the brim. We can’t stress enough how important it is to book your trip as far in advance as you can.
