Delaware River Report: June 7, 2025

Both reservoirs are still spilling. The release from Cannonsville is 600 cfs. There is just under 630 cfs spilling. Most of the heavy storms slid North of us and the rivers look good this morning with just a negligible bump in flows. Today looks like another good day with some possible light showers early, cloud cover, and light wind. We may see some sunshine this afternoon. There is still a wide array of mayflies hatching plus caddis. Sulphurs have been the largest hatch so definitely have that box with you. Nymphs and streamers have been the best bets early.

Today will be 74 degrees with clouds and some rain showers in the morning. Total rainfall should be .04″. Wind will be 5 – 10 mph from the North.
