Delaware River Report / Conditions June 25, 2016

We had another small release bump from Cannonsville Reservoir overnight.  The current release is 599 cfs until further notice.  This is likely due to downstream flow target needs.  We had decent mid-afternoon hatches of sulphurs on some sections of river yesterday with a few cahills and isonychias thrown in for good measure.  Other sections were quiet until evening when the sun dropped behind the hills.  The algae is making nymphing tough on the upper West Branch but it has been working on the lower sections.  Swinging isonychia wet flies has been working in the riffles before the hatches start.
We are back in a warming trend with air temperatures approaching the high 80’s today.  Winds will be less than 5 mph.  The cool nights have been helping and we should drop back into the 50’s this evening.
