Delaware River Report: September 11, 2023

The river flows are dropping despite a few rain showers overnight. The rivers look good this morning – clarity is fine. There were some olive and sulphur hatches on the upper river yesterday giving some people dry fly shots. Nymphing and wets will still be best on the lower West due to the algae up top. The upper East is in great shape with no algae. The overcast sky and cooler air temps should help the water temps on the lower East and Mainstem.

Today will be 73 degrees. There is a chance of morning thunderstorms turning to cloudy skies in the afternoon. Wind will be light and variable.
