Delaware River Report / Conditions September 16, 2015

The sun popped out again yesterday making nymphing the most productive technique until the sun dropped behind the hills.  We did have some small olives hatching mixed with a few flying ants.  We are coming off another cool night so river temperatures look good this morning.  Today will be sunny again with air temperatures in the low 80’s.  We should drop back into the 50’s again tonight which will be good for the system.  We should drop back to cooler daytime temps over the next couple of days.  You can feel Fall in the air.  Once we get a cool down we should see better hatches of fall isonychias, olives, and heptagenias.
