Welcome to the forum! Where are you located in colorado? I've fished from pagosa springs in southwest to horsetooth reservoir in northeast. Echo lake near pagosa was some of the easiest fishing I've seen. Senkos, flukes, swimming flukes, tubes, skinny dippers, toads, frogs, craws, just about anything I had with me seemed to work. I would especially recommend senkos and gitzits. Fish them s-l-o-w on 8-10 lb flouro.
