Thanks for the responses, especially the tip about letting enough line to equal 3X the dept of the water. To help me get out the right amount of line I think a marker on the fly line would be helpful.
We were out in a boat with a trolling motor when we (me and my brother) went to this spot which is quite far out on the lake.
I'd like to try fishing this spot with a fly rod for the challenge of it and push the limits of what I know about fly fishing. If I'm sucessful or even if I fail I will know a lot more about fly fishing.
