Delaware River Report/Update 7/23/2011

The release from Cannonsville was increased to 1001 cfs to help keep the river cool during this heat wave.  The temperature change should be minmal on the upper West Branch, and we expect the sulphur and olive hatches to continue as normal.  It will likely take a day or two for the green algea to filter through, making dry fly fishing your best option up top.
