I got a couple private emails regarding delaware river water temps from striper247 folks. I am new to this site for the most part so if this info is redundant or out of line, sorry for the ignorance. maybe jim can put the water flow/temp link on this site. you can get the info for any state.
go to my site at www.ardentangler.org
click on fish reports at bottom
then click on growing list of links
then click on right column for PA water flows
click on real time (highlighted in blue)
this brings you to the state of PA real time data
click on any color that represents your waterway in the state
some stations have water flow in CFS, temps etc...
good luck and have fun
