I have yet to encounter a dark native rainbow in our state. Most of the time the natives are VERY striking in their appearance, they stand out quite well from their concrete reared brothers and sisters.
These are not my pictures but they are all from NH waters
most I have encountered where as you describe far and few between in NH . but they are around , I caught many 4-8" rainbows up north and asked , they do not stock fish that small in the area I was fishing , they were dark in color . may depend on water being caught . thanks for pics nice fish
Curious keep us informed.
Eventually, all things merge into one, and a river runs through it. The river was
cut by the world's great flood and runs over rocks from the basement of time.
On some of the rocks are timeless raindrops. Under the rocks are the words,
and some of the words are theirs.
