It depends -- during the week you have a lot of options, on weekends you might have to locate spots between people. I've fished from the "flight of steps" up at the dam down through Falls road, Masemore, and a little further down. I prefer stretches of fairly shallow water where soft hackles produce well because I'm lazy and I hate pulling boogers off of nymphs on every cast. That's just me though --
It's a good place to just hike up and down and explore.
