Delaware River Report: August 1, 2023

The aqueduct work has been pushed off again. It is now scheduled for Fall of 2024.

The river flows have dropped a bit more along with the water temps. Yesterday’s thunderstorms slid around us and the West Branch looks good this morning. Stick with the same program for now. Midday sulphurs and olives near the dams is the best bet for dry fly fishing during the day. There is still some algae up high so nymphing will be better mid to lower West Branch. Now that the flow has dropped blind casting Isonychias in the riffles (with or without a dropper) can be very effective.

The Beaverkill at Cooks Falls, East Branch at Fishs Eddy, and Mainstem at Lordville temperatures have dropped a bit with the colder air temps. Please check them with thermometer before fishing.

Today will be cooler again hitting 72 degrees with mostly sunshine. Wind will be 5 – 10 mph from the North.
