yeah we went to the masemore water trail (where there is a parking lot), and went up river from there. You may want to stop into backwater, Theo was great, and the shop has all the flies you'll need. I'd offer to meet you there, but I think I have something planned but I may blow it off, will let you know if that changes.

You'll be dead drifting weighted nymphs mostly, treat your tenkara rod like a euro nymphing rig and you should have fun, plenty of videos on youtube about that technique. You may want to also try trowing dry flies in riffles, but talking with a buddy who guides up there (and who I completely forgot to call before going up there) most of the bugs have been washed out with the high current so you may also want to try streamer fishing, although that is better done with a traditional rod.
What rod did you go with? I'm a big fan of the Tenkara USA Sato as an all arounder but I left mine with a guide in Argentina a few years back and picked up a dragontail hellbender and a komodo. I've landed some 18in+ fish with the hellbender, and the komodo seems to be a good all arounder, although a bit over powering for 4-6in fish. I've also got a little 6ft diawa micro fishing rod that is about the size of a wizards wand when packed, great for tossing in my nathan's running pack. I used to run 7miles to lake needwood and fish the outflow there while I cooled down, and then run back after fishing for a bit.
