Delaware River Report: April 30, 2025

We had a few brief rain showers but not enough to noticeably bump the river flows. Water temps are starting off at a good place today which may push the hatches a little earlier. Hendricksons, blue quills, olives, and Quill Gordons are still all in play. Some river section are seeing the smaller #16 Hendricksons too. Caddis are still around in good numbers so watch for sporadic rising even before the mayflies hatch.

Today will be 60 degrees with a partly cloudy skies. Wind will be 10 – 15 mph from the North.
