That's a bummer about the Esopus- I read an article in the TU about it last week... Sounds like all the southern streams will probably ended up coated in green goo before too long...
There still seem to be mixed reports about it's effect on biomass/bug life, etc. but regardless it sure makes fishing a lot tougher...
As for the Upper Rondout- it is as pretty a stream as there is in the Catskills. I lived right by there (over Red Hill Road) when I ran the Straus Center for Frost Valley... That stream get HAMMERED by the NYC crowds that camp along Peekamoose Road every summer weekend and swim near Buttermilk Falls.
It's a shame, really, since the brookies in there are BRIGHT!!!
The Neversink above the reservior is cherry on the Frost Valley land (private- and I managed six miles of it for my fly fishing school and fishing membership) but sparse access anywhere else except the end of Denning road, and the fishing is weak there on the State land.
PM me next time you head down and I can steer you into the NYC DEP land where the old "Big Bend Club" used to stand. The walk is pretty easy, the scenery excellent, and the fishing can be HOT!!! Nice browns and brookies in the riffles, and giant Smallies in the deeper pools. The water is crystal clear- here is what it looks like:
The Smallies grow big in those Reservoirs with all those tasty sawbellies to munch on!
We should team up on a trip down there sometime this summer, Yank!
If you haven't fished the "Neversink Gorge" yet than we should do that too! NICE browns and we even got a Tiger Trout down there the night before I moved to Albany!
Craziest trout I have ever seen... It was a bloodthirsty predator, lemme' tell ya!
