Delaware River Report / Conditions August 24, 2018

The flows are dropping nicely and the rivers look good this morning.  The release from Cannonsville is still 1,500 and will probably stay there until the reservoir levels drop a bit.  The flow at Hale Eddy is 2,370 and dropping slowly as the feeder stream flows drop.  The cold releases and cooler nights have helped the water temps throughout the system.  We should be in the 70’s with a bit of sun today but the night temps are dropping back into the 50’s.  There’s no appreciable rain in the forecast so we should continue to see the river flows drop over the next few days.  We’ve been finding quite a few olives on the West Branch mixed with a few isonychias.  Streamers have worked well in the higher flows.
