    I caught this fish today on the S. Fork of the Snoqualmie River, east of North Bend. Most fish I catch on this river are between 6" - 10", thus this guy caught me by surprise. This rainbow was a legit 20". I am wondering, how long would it take to grow to this size, on this body of water?

    cheers bro, I believe that is equivalent to a 20 lb steelhead for that system.

    I've seen 20" brookies but never rainbow that approached that size on the SF. Congrats and keep that spot under your hat. Now I'm all antsy to go and scout, heck that photo is giving me the Jimmy legs!!!

    wow, that is a fine, beautiful specimen! well done there squaretail! big fish are a combo of food sources and genetics, that fish appears to be around 6 years old. as they get older they tend to start developing a rugged look with defined, hardened facial features. that fish doesnt really have that going on, it could be right out of the madison! what a fish!

    You sure that it isn't a steelhead that jumped Snoq Falls? :thumb: :beer1::beer1:

    :beer2: hamana-hamana-hamana . . . . that is a nice fish anywhere but has to be close to a (if not the) modern day record on that river.

    It's a steelhead that jumped Snoq Falls. :rofl: That I must agree is the best answer. Must be at least 4 or 5 years old.

    Very well could be a steelhead, as there is a private Hatchery on the south fork up one of the feeder creeks that raises them,and it couldve escaped .

    Maybe. Looks pretty healthy for a hatchery ecsapee though, unless it's survived in the system for a few years after.

    my guess would be 5 years, maybe 6...looks more like a lake fish rather than a river fish. 7-8 months of heavy flows a year....with a big fat belly....could it have escaped from a lake near by?

    TM, I think an escaped steelhead would have had the urge to jump the falls...heading west. And I am pretty sure that the genetics of steelhead don't cause them to get bigger than riverine bows, rather its food supply. More yummys in da ocean.

    The fins look to be in good shape, so if it was an escapee, and therefore hatchery origin, it looks to have been away from the concrete for a few years.

    My guess is its a damn nice, damn big native rainbow! A fish of a lifetime for that river. Catching that fish is rarer than catching a 50 pound king or a 20 pound steelhead!

    that fish is wild, and appears to be child of moving water.

    An exceptional fish for the Snoqualmie Forks for sure!!

    Based on the ages I have seen on western Washington resident rainbows that fish could be any where from 6 to 10 years old. More likely 10 years od than 6 unless it was one of those lucky fish that found some exceptional food sources.

    BTW - Looking at the tail fin rays I doubt the fish has never seen a hatchery.

    Tight lines

    I judged fish growth by head size. If they have slower growth the head is usually bigger. If they have a smaller head and bigger body it usually indicates fast growth. This can be a good way to indicate age. It has a fairly normal head size. I am surprise that a fish that large was in the system above the Falls, which we all know eliminates steelhead, but it does look like a steelhead. Just a very pretty fish and very rare indeed.
