Delaware River Report: July 31, 2022

There was another cold water pulse from Cannonsville overnight. Less water than they pulsed last week so it shouldn’t be noticeable when you’re on the river. Yesterday was bright with a little more wind than we would have liked but there were sulphurs and fish eating in the coldest sections of river. We have some fog this morning and should have some cloud cover once that burns off. Small sulphurs, followed by small olives made up most of the hatch. There are cahills and Isonychias around too. Nymphing and swinging wets has also paid off mid day. Cloudy, 83 degrees, and light wind.

The East Branch at Fishs Eddy, the Beaverkill at Cooks Falls, and the Mainstem at Lordville all peaked over 70 degrees yesterday. Give these sections a break until we get cooler temps.
