Delaware River Report: September 6, 2026

The release from Cannonsville is 450 cfs. The rivers are in good shape this morning. The West is at a decent level for floating and wading. The clarity is good. Olives and flying ants should be back on the menu along with some hebes, Isonychias, and Cahills. We’ll see if the high flows flushed the algae out of the Upper West but it’s probably still safer to stick low if you want to nymph or throw streamers. The Beaverkill, Lower East, and Main are still high and off color. They’ll take a couple of days to get back to normal.

Today will be 72 degrees with a mix of clouds and sun. Wind will be 5-10 mph from the North.
