Delaware River Report / Conditions June 28, 2016

We finally received some rain yesterday after what seems like a very long dry spell.  Most of the precipitation soaked into the ground but there is enough runoff to raise the rivers slightly.  There is no color in the system this morning and the rivers are still in decent shape for wading and floating.  The water temperatures dropped lower overnight with the cooler air temperatures.  The West Branch and upper East Branch are still in great shape.  The lower East Branch and the Mainstem both had water temperatures peak over 70 degrees yesterday so avoid those rivers despite the slightly lower water temperatures this morning.  Sulphurs, cahills, olives, and isonychias are still on the menu with #16 – 18 sulphurs being the most common mayfly we are seeing.
We have cloud cover this morning with some more rain in the forecast.  This could push the hatches up a bit during the day on the lower West Branch and bring out more olives.

The inflow at Walton increased slightly with the rain. Hopefully we get more rain today
