The water levels are still falling throughout the system as the runoff subsides.  The release from Cannonsville remains the same over 700 cfs.  The cold release and cloud cover should keep the West Branch in good shape today. We’re back in the pattern of potential afternoon thunderstorms.  We should have clouds early with the chance of storms starting around 2 pm.  Hopefully they miss us.  There is still a lot of water coming into the reservoirs so keep an eye on the Downsville and Stilesville gauges for potential spill over the next few days.  Blue Wing Olives, sulphurs, isonychias, and some cahills will cover most of the mayflies.  We’ve been seeing some tan caddis lately too so carry a few of those.
