How do you fly fish with a Nymph?

I think it has something to do with letting the nymph sink to the bottom, but then wouldn’t i need a seenking line?

fishing a nymph can be one of the most productive fly-fishing techniques. you can fish a nymph with a floating line but you don’t cover as much of the different depths as you would with a sinking line. i do use a nymph and floating line often when I’m fishing streams. still waters you would need to have a full sinking line to properly present the fly. i like to cast along a drop off and count as i let it sink that will give you a rough idea of where the fly is when you strip it in on the retrieve. varying the amount of time you let it sink will allow you to fish different depths and when you find where the fish are you can count out and get your fly back into the same basic depth.
good luck
