The Upper Delaware River is rather low. The Upper East and West Branches of the Delaware River have the coldest water, with temperatures rising as you go downstream. The Main Stem Delaware River was too hot to fish a couple days ago, but has cooled down since. The dry fly fishing is slowing down, but you can still have hatches of BWO's, Sulphur's, Caddis, and the occasional Green Drake or large Cahill. The nymph bite has been pretty solid in between the bug hatches. Our Delaware River trout will eat a variety of nymphs. Be safe out there!
