Fly Fishing Rochester NY

Well, ive posted here a couple of times, and i probably bugged the hell outta all of you by asking so many damn questions about fly fishing. Well, i bought a pole, bought a video, and ive been fly fishing for the last week or so, and im doing good actually. I havent caught anything yet, but that usually doesnt matter to me. I like to go to Irondequoit creek (even though theres way more salmon then trout in there), and its very pretty there. So if i dont catch anything, its always a fun day on the creek. But heres what I have to ask.
Does depth have anything to do with fly fishing. Ive been thinking, and id guess that if your trying to fly fish in like 10 feet of water, you wouldnt get anything, simply becuse if the fish are down lower, they either cant see or just wouldnt come up for a fly. So I guess my overall question would be how low are the fish swimming in this time of year? And also, Has anyone ever heard of places like Oak Orchard Creek, Johnson Creek, Oatka Creek, and
Irondequoit Creek? Any info on the fishing there would be great for me.
Thanks for any help. My IM is DMBphish1234 so if you could IM me or else just post on here, thatd be awesome. Sorry for the long post.

I can't comment on the rest of your post, but the answer to this question is 'Yes'. If the fish are on the bottom eating well, they probably will respond best to something on the bottom. And since most of the food is on the bottom, the fish will be too most of the time.

If you mean you're fishing dry flies in 10 feet of water, and you don't see any fish rising, then it's less likely that fish will come to the surface than be caught underneath. But 10 feet is pretty deep to be fly fishing in most streams anyway, even with nymphs or streamers. You can find easier water to fish than that

Sometimes bugs hatch in cold weather, but if you don't see them, then the colder the water is, the better off you are fishing on the bottom with nymphs.

Start fishing Oatka Creek. Go over to Carl Coleman's fly shop and ask some questions and they'll get you pointed in the right direction. Hiring a guide can also be a good education for learning how to fish the area.
