Delaware River Report / Conditions September 17, 2017

So the release from Cannonsville has been cut back and it looks like we are back to 300 cfs this morning.  We peaked just under 700 cfs last night.  This doesn’t seem like the most spectacular move in the history of river management.  This seems like a good opportunity to try ramping the flows up and down. The higher release added color to the West Branch and knocked loose a lot of algae on the upper section by mid afternoon.  We should clear up today and have way less junk in the water as it all filters out.  The flow at hale Eddy is still dropping this morning but should level out soon.   The flow on the lower Main is still rising this morning but we should see that peak and drop this afternoon.  Yesterday was a mix of flying ants, some olives, cahill / stenos, and heptagenias in the evening but the bugs were spread out in the higher flows.  Nymphing seemed to be the best option.  smaller nymphs and wet flies seem to be working best matching the size of the olives and heptagenias.  Today should be another warm one with a possible storm in the afternoon.  Precipitation should be light under 1/10th”.
