Delaware River Report: May 2, 2025

We had some blog log in issues yesterday but everything seems to be working well this morning. Today looks good with clouds and decent water levels and temps. The wind has been a problem this spring and will continue to be today as these fronts move through. Look for wind protected banks if it picks up in the afternoon. We’re seeing decent numbers of caddis in the morning followed by a mix of bugs in the afternoon. Olives, Hendricksons, and blue quills are making up the bulk of the mayflies but there are some March Browns beginning to show on some river sections.

Today will be 79 degrees with cloudy skies early clearing to partly cloudy skies in the afternoon. S stray shower is possible. Wind will be 10 – 15 mph from the South.
