As far as catching fish, that river gives me a fit. It is difficult. Only stream I know that has one section called the PHD Hole. I know good fisherman that won’t bother with it.
As far as bugs go, the pickings are pretty slim. The local TU group samples various streams per The Univ. of Md. to collect insects for their research. We did the upper Savage, and three tribs. We found plenty of caddis, mayflies, and stones. Also, crayfish, muddlers and other minnows. We checked one spot on the Lower Savage and two people found only a couple of nymphs. They know what they are doing and should have found more. We saw one fish rising. One friend of mine used an olive wooly bugger and caught some browns by keeping the bugger close to the surface.
