Delaware River Report: October 17, 2026

The release from Cannonsville is 150 cfs. The release will remain low while the runoff makes it’s way downriver meeting the Montague flow target. Check the Stilesville gauge link below for the most up to date information. The flow at Hale Eddy is 420 cfs. Yesterday’s rain added some more runoff so the rivers are up from yesterday. It’s going to be much colder with wind to day so keep that in mind when you plan. We’re back on a warming trend tomorrow and the rest of the week looks nice. We’re mainly fishing small olives. Nymphing and streamers are putting some fish in the net early with the hatches coming in the afternoon / early evening. There are some Isonychias and caddis around – plus a few hebes.

Today will be 48 degrees with light rain in the morning and becoming sunny in the afternoon. Wind will be 10 – 20 mph from the North.
