It doesn't actually relate to your fish, but I've recently gotten information about a small stream in my area that is said to hold some very large Brook trout. It's never been a stocked stream and would be miles above any stocked portion, but it's my belief that if there are fish of the sizes that have been alleged, that they surely must have come up from downstream and lived in there for years. I've simply never seen native brookies of the size that's being mentioned and the person that told me about this is a reliable source. I actually went on a short scouting mission myself and only hooked wild browns, although I did break off a fish that was very large and which I didn't see. I'd love to think it was a wild brookie, but who knows.
