Delaware River Report: April 20, 2025

People had some success dry fly fishing yesterday. Olives, little black caddis, Blue Quills, and even a few Hendricksons showed up. The wind was tough but there were enough breaks that the let the fish get happy. Nymphing also worked during the windy periods. A few decent thunderstorms pushed through in the late afternoon. The river flows bumped slightly from the rain but not enough to be noticeable. Today will be cooler but still respectable at 56 degrees. Wind may be an issue again but hopefully we get some breaks again.

Today will be 56 degrees with a mix of sun and clouds. Wind will be 10 – 20 mph from the North.
