I'd say these are monster brook trout in the 16-19 inch range and grossly obese, struggling to stay right side up. Shot this video while fishing the Eastern Sierras, Kirman Lake. If anyone knows where I can find some of these in Alberta I still need to catch one as all I caught was the images of these fat slobs this time. I know there is a lake... Fortress Lake In BC that is known to hold some monsters, maybe I'll have to go in search of them there.
Anyways here is a pic of what they look like from this lake... if I would have caught one.
Here is the video link which I think is more fun to watch than catch them anyways... jk!
