Delaware River Report / Conditions September 12, 2015

The low water and bright sun made yesterday tough.  The release from Cannonsville Reservoir continues to be 401 cfs until further notice.  Nymphing on the West Branch was definitely the best technique during the day until the olives and small sulphurs hatched towards dark. The low water and bright sun also heated up the Mainstem and lower East again with both rivers having water temperatures peaking at 70 degrees or above.  Today should be cooler with air temperatures in the low 70’s.  Accuweather is calling for 1/4″ of rain to fall sporadically throughout the day followed by just under 1/2″ overnight.  Small olives, small sulphurs, a few isonychias, and a few cahills will cover the majority of the hatches.

Look for the shaded banks until the clouds roll in today
