Delaware River Report / Conditions July 24, 2015

The hatches started a little later yesterday due to the bright sun but most of the system had some kind of decent activity by mid-afternoon into evening.  The upper river sections have more sulphurs and olives while the lower / warmer river sections have more cahills, isonychias, and golden drakes.  Streamer fishing has been productive early in the morning before the fog burns off.  The high cold water has really benefited the system after the low water Spring.  The fish are healthy and full of energy.  Many of the July hatches on the lower sections of river usually occur at night due to warmer water temperatures.  This season we are seeing those hatches during the day because the cold releases and cool nights are keeping the system cold all the way down to Callicoon.  It’s been a nice side benefit to the repair situation at Cannonsville Dam.  It sounds like we should see the higher releases at least for another 3 to 4 weeks.
