Upper Delaware River Report — June 30, 2010

Cooler air is here, and it has already taken effect on the water temperatures which are down a couple of degrees all across the board.  Night time lows below 50 degrees should only help to further cool it down.  Today’s forecast shows bright sun all day, with no chance of rain.  However, with the cooler water there should be consistent bug activity throughout most of the day.  Yesterday evening brought a great Sulphur hatch, as well as Olives, Isos and Caddis.  Today should bring much of the same, and should be a good overall day for being out on the water.
