Caught in the Park...close to 20" but not quite...(and not stream reared...
There are numerous streams in the Park that host lake-run fish, both rainbows and browns. There are definitely big rainbows in the Park but true wild rainbows that size that are not
lake run fish are definitely rare. I think Abrams is probably the only creek in the Park capable of producing rainbows into the 16-20" range and that only occasionally. Wild rainbows on Little River are occasionally caught to 16" or so but again, those are rare... In general, large fish like this came from hatchery supported water at some time in their past. In the case of lake-run fish they have adapted and act very "wild" in their habits but the big brood stock fish that run up from stocking points can actually be pretty easy to catch.
