Delaware River Report: May 4, 2025

We had a few rain showers hit us yesterday but the rivers came through just fine. Most of the storms slid North of us. Today’s forecast is all over the place and changes every time we look. We will get rain. Right now it looks like a half inch spread out over the day. There may be some localized heavy rain but there is no way to predict where those cells will hit. If they slide around us again we should be in decent shape. Just keep an eye on the radar and check the weather reports. The wind will be low again compared to what we’ve been experiencing. We’re still seeing blue quills and Hendricksons on some river sections while others have transitioned to March Browns. There are still a lot of caddis around too.

Today will be 64 degrees with rain. Total rainfall during the day should be .5″ to .75″. Wind will be 5 – 10 mph from the East.
