Kenai River king salmon fishing is by far the most popular trophy fishery in the entire state. And there is little doubt that the words Kenai River immediately bring visions of record-breaking fish and fish racks filled with trophies hanging next to smiling anglers. Every year the largest king salmon in the world begin to enter the mouth of the Kenai River. Kenai River king salmon average 40 pounds. On most rivers a 40 pound king would be a trophy, but here we expect them. The world record king salmon was caught by Les Anderson on May 17, 1985. This king weighed in at a whopping 97 pounds and 4 ounces (44.1kg). Each year 70 and 80 pound kings are caught on rod and reel in the Kenai River. 2009 saw a king released that was estimated in the 90 pound range! The Kenai River has produced 8 out of the largest 10 king salmon caught on rod and reel.
