We’ll watch how those storms track. 83 degrees with wind 5 – 10 mph from the South.

Some sections of river had a decent fall of flying ants last night. Very small ants but some got on them in the flat water. They were mixed with the small olives as the sun dropped. We also saw a handful of steno / cahills and a few Isonychias. We’re seeing some tricos out there in the mornings. We haven’t had great reports on them yet but it’s worth having a few in your box. The release from Cannonsville stayed steady overnight at a reasonable 650 cfs. Good for wading and floating. Today will be a bit warmer hitting 85 degrees with sunshine. Wind will be light and variable.

They pulsed from Cannonsville around midnight and the flow at Stilesville is 722 cfs and falling. We’ll settle back into the500 cfs range. So the West Branch is in decent shape for wading and floating and the level will be dropping slowly this morning. We had some rain last night but it wasn’t enough to bump the flows. It did push small olives and most people found rising fish. It was still #18 and #22 olives for the most part although there were a few cahill / stenacrons and Isonychias on the water. Today will be sunnier hitting 82 degrees. Wind will be 5 – 10 mph from the North.

The release from Cannonsville was increased slightly and the flow at Stilesville is 515 cfs. Not a big jump so the West Branch will look pretty much the same as yesterday. We had a few brief periods of rain but it soaked into the ground The larger thunderstorms missed us. Most of our fish were caught on small olives yesterday. There are still some sulphurs around mixed with cahills and Isonychias but the fish we found were on the little olives. We have some fog this morning and should see some rain showers today. Total rainfall should be a negligible .12″. 78 degrees with wind 5 – 10 mph from the West.

The release from Cannonsville was cut back to about 500 cfs. DEP is likely counting on the rain to meet the Montague Flow Target. If the rain misses or soaks into the ground we expect the release to increase. It’s going to come down to which way these storms track. We have some light rain falling this There may be some heavier thunderstorms developing but right now Wunderground is calling for .32″. Wind will be 5 – 10 mph from the South. If you do fish today keep a close eye on the radar. Small olives and a few sulphurs worked well yesterday. There are also Isonychias and cahills around. We’ve seen an odd flying ant here and there but nothing major yet.

The release from Cannonsville was dropped but is now coming back up. It’ll likely settle back in around 1,100 cfs. We had some rain in the evening but it soaked right into the ground, DEP was likely counting on it adding more water to meet the Montague Flow Target. When that didn’t materialize they raised the release again. So we’ll probably be about the same as yesterday with spots that are good to wade and decent floating. Small olives are still our #1 mayfly with a few sulphurs mixed in. Cahills and Isonychias are definitely around too. It’s also the time of year to have a few flying ants in your box just in case. Today will be 86 degrees with clouds. Wind will be 10 – 15 mph from the South.

They did some minor adjustments to the Cannonsville release yesterday afternoon but we are essentially starting this morning off the same as yesterday morning.
