Delaware River Report / Conditions October 2, 2015

It looks like Hurricane Joaquin’s path is taking it out to sea so the Upper Delaware System should come through this weekend just fine.  The release from Cannonsville has been cut back to 150 cfs while the runoff satisfies the downstream flow targets.  The nights have finally turned cool and it feels like Fall.  We had air temperatures in the 40’s last night so the rivers are starting off cool this morning.  Much of the runoff up here has subsided and the clarity is decent.  We should have cloud cover for most of the day with moderate winds and a few gusts in the low teens.  We may see a little rain moving through overnight but the precipitation totals look negligible in the forecast.  The West Branch looks decent for nymphing this morning until the small olives hatch in the afternoon.  The cooler weather should begin to push the Fall hatches soon.
