Hello everyone!

I am wondering about the differences between brown or generic trout flies for rivers/stream and lakes.

There are lots of ponds (aka lakes) here that have trout in them, but it seems that most fish for trout in streams. So I am wondering what are teh specific differences I am looking at for choosing proper flies for trout that are on ponds/lakes.

First off, I am thinking that there may be no difference, and then second I think that maybe streamers may be of more use then nymphs.

Could someone place clairify this for me please, i would greatly appreciate it! Also ifyou know any great patterns that would be killer.

Thanks a lot everyone! I really appreciate it.
