Delaware River Report / Conditions June 27, 2011

Confusion. That pretty much explains yesterday here – starting around 11AM, we saw an epic hatch of pretty much everything mayfly, and it ran until 3PM – the only problem was that there were very few fish taking advantage of the situation. In the evening, we saw almost NO activity from either the bugs or the fish. Our current theory is a change in pressure  that put the fish down (high pressure moved in). Now that it has stabilized, we should hopefully be back into our ‘normal’ pattern! The good news out of yesterday is how many species of Mayfly we still have kicking around – dorthea, invaria, cornuta, deficiens, pseudocloeon, stenocron, ithaca, isos, etc., etc.


This is what they did yesterday. Sat there. Awesome (Insert sarcasm here). Photo by: Jeff White
