Delaware River Report / Conditions August 20, 2016

We have had pretty consistent flows and temperatures for most of the Summer.  It finally looks like we’re going to get a night time temperature break down into the 50’s beginning tomorrow. This should help drop the water temperatures and hopefully increase the hatching activity on the lower West Branch.  We may get some light rain tomorrow but the total precipitation should only be around 1/4″ .  The cloud cover should make the fish feel more comfortable mid-day.  We will have to deal with sun today with air temperatures in the mid 80’s.  The winds look good staying below 10 mph.  Sulphurs, isonychias, cahills, olives, and a few golden drakes are still the main food.  We are seeing a few more caddis showing up in the evenings.  We are finding a few flying ants around and the fish are eating them.  We are due for a major ant fall – we’re all just waiting for the right conditions.
