Delaware River Report: April 21, 2025

The wind made things tough yesterday but there were some breaks that allowed people to capitalize on caddis and some mayflies. The air temps look great this week and we should see the water temps hit good numbers in the afternoon. that should push the Blue Quills and Hendricksons. There are olives and Quill Gordons out there too. The caddis have been active in the mornings before the wind picks up and in the afternoons if the wind drops.

Today will be 60 degrees with partially cloudy skies becoming cloudier in the afternoon. Wind will be 10 – 20 mph from the South.
