Delaware River Report: April 25, 2025

Today will be another warm one but with clouds. Wind will be the same as yesterday so not bad. The warmer air temps and sunshine bumped the water temps quite quite a bit. The amount of caddis around is pretty amazing. It’s mostly appels with some little blacks mixed in. We are seeing olives, blue quills, Quill Gordons, and some Hendricksons. Things are shaping up well after an unsettled early Spring.

Today will be 76 degrees with clouds. Wind will be 5 – 10 mph from the South.
