Delaware River Report: April 19, 2025

We had the bugs. Yesterday some river sections saw a mix of Hendricksons, Blue Quills, Olives, and Stoneflies. There were also some little black caddis around. The heavy winds pretty much defeated everyone and forced a nymphing day. Water temps look great, the bugs are getting better and better, and the rivers are in good shape for wading and floating. We just need a break from the wind. The river temps are up this morning and should climb today despite the clouds and light rain. Try to hide from the wind. It’s tough to hide without the leaves on the trees but look for sheltered edges, side channels, and bends below islands.

Today will be 80 degrees with cloudy skies. We may see some scattered thunderstorms in the afternoon. Total rainfall should be .1″. Wind will be 10 – 20 mph from the South.

Water temps are great for mid April
