Delaware River Report / Conditions September 19, 2017

The Cannonsville release was dropped to 225 yesterday.  This morning it was brought up to 240 cfs.  The low water and bright sun spiked the water temperatures on the lower West Branch and Mainstem.  Definitely check the water temperatures today before you fish the West and we should avoid trout fishing on the Main altogether.  Unfortunately this situation seems like total unnecessary political posturing as the decree parties try to come to a flow agreement.  While we’d love to see an agreement signed that is mutually beneficial to all river users, putting the downstream ecosystem in peril to prove a point seems reckless and spiteful.  The current storage for the NYC Reservoir System is 84.4%.  Normal storage for September 18th is 76.6%.
Please let the principles know that protecting the river ecosystem is much more important than some political posturing / power play:

We should have cooler weather today but that is relative since we’ve been in quite a heat wave.  The air temperature will peak around 78 degrees.  We should have sunshine for most of the day.  We do have some heptagenia and olives on the buildings this morning.
