Ok, me again, I just posted about fishing from a float tube so let's assume for a second I do get one... I am curious about nymphing from a tube as I have never done it. I have just generally always fished streamers or dry. Now I know it's a bit warm right now which won't make our lives any easier but we're fishing a dam outside Notties in a couple of weeks.

This may seem like a stupid question but here goes anyway. If I was to drop a nymph off a dry and use the dry as an indicator, how far out do I need to cast? Obviously the further away from me it is, the harder to see. The closer to me, the less likely the fish will take?? Or not?

Any other tips will be helpful! Thanks

Thanks
