Delaware River Report: April 17, 2025

We’re back on a warming trend and everything looks great trough the weekend. We’ll have some wind to deal with but that’s a small price to pay to have air temps back in the 50’s to 60’s. The water temps are starting off today a bit low due to the cold and cloud cover yesterday. The air temp and the sunshine today should push them back up by mid afternoon. Olives, little black caddis, and stoneflies should be out. Look for wind protected areas and take advantage of any breaks. Blue Quills should start to show with this warmer weather. Nymphing or streamers will be the best bets early.

Today will be 54 degrees with plentiful sunshine. Wind will be 10 – 15 mph from the North.
