Delaware River Report: September 17, 2026
The release from Cannonsville is 475 cfs. Today looks like a good day to be on the water with rain early, clouds, and maybe some afternoon showers. Total rainfall should be less than 1/4″ today. So it definitely looks like an olive day. Streamers could be a good bet with the rain and the color of the West Branch. The West Branch is at a good level for wading and floating. There have been tiny olives on some sections and a few Cahills, Isonychias, and hebes. The hatching should be less spotty as the flows drop and the nights get cooler. Streamers and nymphs are good bets early and late in the day. The West Branch has a greenish tint to it that is likely the reservoir turning. The fish and bugs don’t mind it and its actually better for streamer fishing
Today will be 76 degrees with rain early. Total rainfall should be .17. Wind will be light and variable.

Hopefully we get some precip and it pushes the bugs a little earlier in the day. Olives and flying ants are still the main bugs but there are some Isonychias, Cahills, and hebes around. Blind casting the larger bugs in the riffles can pay off. Nymphs and wets have been putting some fish in the net too.

The release from Cannonsville is 475 cfs. The mornings have been chilly and it feels like Fall is coming. That should be good for the river system. We’ll have some sunshine today but should get some clouds back tomorrow. Olives and flying ants are still the main bugs but there are some Isonychias, Cahills, and hebes around. Blind casting the larger bugs in the riffles can pay off. We’re dealing with bright sun today so streamers will work best before the sun hits the water or after it drops this evening.

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.
