Delaware River Report / Conditions July 30, 2016

The East side of the drainage has dropped back to pre rain levels.  The West side of the drainage is pretty much a mirror image of yesterday.  We should be much cooler today with the possibility of thunderstorms in the afternoon.  We’re not sure what to expect since they seem to be changing the forecast every hour.  Right now they have us at 80% chance again.  The only thing we can do is pack the rain gear, wait and see.
The mid afternoon sulphur hatches continue on the upper river sections mixed with olives, golden drakes, and a few isonychias.  If we get the rain we should see brief but heavy olive hatches on the lower West Branch.  Nymphing has been productive in the mornings before the sun really beats down on the water. That should last longer today if we keep the cloud cover.
