Delaware River Report / Conditions July 9, 2020

There were quite a few isolated storms yesterday and we finally saw some rain on the lower West Branch.  There was a small bump in flows but most of the rain soaked into the ground and the river flows are starting out roughly the same as yesterday.  Some sections saw some color in the river but it cleared quickly.  The release from Cannonsville has been cut back.  The release hotline says 699 cfs but the flow at Stilesville is 540 cfs so it is lower than the recording says.  Today is going to be a hot one hitting 90 degrees.  There is a 10% chance of storms but we’ll mostly see sunshine.  Wind will be 5 – 10 mph from the South.  We should cool down and see some more rain showers over the weekend.  Sulphurs and olives are still hatching with some isonychias and cahills mixed in.
