The Yampa has been the same ol same old this spring (in a good way.) Fishing has been consistently good with the usual crowds.
Nymphing with midges and small baetis will yeild the most fish.
I would strongly encourage a lot of fishermen to try dry fly fishing on the Yampa right now. Almost any size 16 and smaller dry fly with a good presentation will yeild fish. Look for risers from mid morning on in the side channels and in front of rocks.
