The deep subsurface canyons of Blue Mesa Reservoir provide excellent habitat for the big lake trout or mackinaw. The “mac” can reach tremendous sizes - one monster weighed forty-six pounds! To catch one of these “big ones”, you must fish deep and in cold water. Brook trout live in most of the streams which feed the reservoirs of the recreation area. Curecanti Creek, which feeds into Morrow Point Reservoir, can be one of the best spots for catching the “brookies”.
