Delaware River Report / Conditions September 13, 2012

No big drop in flows last night, just down to a 464 release which should not dramatically affect the hatching, holding areas, etc. It will allow downriver to warm up a bit more (especially with 80-degree temps predicted), so we will likely “lose” the lower Main today insofar as decent hatching is concerned. The entire West Branch fished fairly well, but the Main as a whole was pretty slow until the sun started settling in the evening. Then Junction through Stockport produced, but below Cemetery Pool not much was seen other than everyone’s favorite – the river chub feeding on Heptagenias. Today we are looking at warmer (air) temps, but there are supposed to be clouds mixed in as well, unlike our Rocky Mtn. Bluebird day we had yesterday. This is definitely good news for those of you looking to fish the afternoon, so get out there and get after them!
