Ok, that helps. On the water at 5am will equal a hatch of nothing (most likely). You may find a handful of garbage feeders cleaning up the previous nights spinners. If you wait until a little later, you should see the small summer sulphurs, a few caddis, maybe some olives or isos. Later in the day the stenos and isos will be more prevalent. As standard on the Delaware......in a pool with rising fish, you'll see a bug you never expected. In a pool with no rising fish.....the guy in the next pool has hatches galore.
Since you've only fished up there a few times, be careful at these flows. I'm guessing that any additional rain will cause flows to jump up and reduce visibility as Ocagua will likely dump chocolate milk into the system. If that's the case, Stilesville will be your only clear water and you'll have to join the 40 other guys jockeying for a rising fish.
With that said, a big bump in the flow or reduction in the flow means toss everything I said out the window. As a general rule, the closer to you get to the dams the cleaner the water will be in the event of heavy rains. Each branch has a feeder that dirties the water in the first couple of miles. Many times, the upper east is a good alternative. Keep an eye on the flows and the radar. I'll be doing the same as I hope to get there and fish Sunday and Monday. I intend to fish an entirely different section as I don't care for the crowds on the west.
