The Release hotline is saying we have a release from Cannonsville of 461 cfs this morning.  The Stilesville Gage is showing a flow of 391 cfs.  It has been around 8 hours since the last flow yo yo so I guess someone felt it was time to mix it up.  The runoff and releases from Wallenpaupack and Rio must be meeting the downstream flow requirements so we have been cut back again.  This winter we’ll put up some posts looking at how often the Upper Mainstem hit 70 degrees,   how they gradually ramped the flows up and down (or didn’t), and how often they let the temperatures on the lower West Branch climb unnecessarily high.  We could also look at all the days the West Branch releases were very high while the East Branch was dry and hitting 75 degrees but I’m not sure we have enough bandwidth to cover that BS.  In November the first thing we should look at is when they released additional water this season, how many times, and why.
We did find some fish eating on top yesterday with a mix of small olives and isonychias.  Some people found success swinging caddis pupa in the riffles.  Today looks like another good weather day with some light rain and an overcast sky.  Winds will be light under 10 mph.
