Delaware River Report / Conditions July 30, 2020

Jul 30, 2020 Comments Off by

Yesterday’s 20% chance of storms turned into 100% after dinner last night.  The rain came down hard for a bit but mostly soaked in the ground so no real flow change.  It was definitely needed though.  Today looks like a great day to be on the water with the air temp only hitting 81 degrees, some cloud cover, and 4 – 5 mph wind from the West.  There is a 40% chance of some afternoon storms but the total rainfall predicted is less than 1/10″.  They did not pulse release from Cannonsville last night probably due to the cooler air temp and potential rain.  That’s great news because the pulses are kind of annoying and don’t really do any good for the river anyway.


The lower Beaverkill, lower East Branch, and Mainstem temperatures are all peaking over 70 degrees.  Give those rivers a break until they cool down.
