Record Rainbow Trout Caught in Idaho

by Game & Fish Staff   |  July 28th, 2011 19

POCATOLLO — There are eatin- sized rainbows and then there are mountin’-sized fish that rewrite record books and provide a fishing tale of a lifetime for the lucky angler that reeled it in.

Mark Adams with his state record trout.

Mark Adams of Pocatello, Idaho is that angler according to the Idaho State Journal as he landed a record rainbow trout weighing 34.74 pounds while fishing the American Falls Reservoir in southeastern Idaho. The record rainbow trout broke the state record by 14.72 pounds and Idaho Fish & Game officials are checking on how it ranks in the lower 48. Accrding to, it might in fact be the biggest.

According to the International Game Fish Association (IGFA), the all-tackle world record rainbow trout is 48 pounds, caught in Lake Diefenbaker, Canada by Sean Konrad.

  • roland martin

    def not an ordinary rainbow. salmon or some hybrid

    • Will Betty

      Roland you are right, it is definately not an ordinary rainbow, it is an extraordinary rainbow! My guess is the old guy led a charmed life in the holes of American Falls reservoir and capitalized on being at the top of his food chain in his neck of the woods. May possibly be a cut-bow, but, I am not seeing any of the visual characteristics. My uncle owns a fish farm and I have seen several rainbows pushing this size in his honey hole! Granted, they were on a high protein shrimp based diet, but they got huge! It is genetically possible.

  • B. Harp

    Steelhead could not surmount all the dams to reach American Falls Reservoir. Congrats, fisherperson! Sure would like to know line weight.

  • Rich Sharp, nor cal

  • Rainman

    Most probably a Triploid bred to grow to massive sizes and be dumb as rocks. Do a search and look at some of those monsters.

  • Liam

    Someone snuck into a fish farm and stole one of their brood fish.

  • Jim Allen
