Delaware River Report / Conditions August 21, 2018

Aug 21, 2018 Comments Off by

The river dropped quite a bit over the last 24 hours but both reservoirs are still spilling.  The Cannonsville spill is hot at Stilesville until it mixes with the colder release and runoff and cools down to 60 degrees at Hale Eddy.  The release from from Cannonsville is 1,500 cfs.  There is 1,211 cfs spilling.  Give it a few days for the runoff and spill to subside a bit more.  The Beaverkill flow has dropped under 1,000 cfs and the temp looks good at Cooks Falls.  There is a chance of rain this morning but the amount looks negligible.  We have a chance of seeing a little over 1/4″ overnight, followed by a little rain tomorrow.  After that we should be dry through Sunday.
