I've fished Smith Creek and the Soque. Smith Creek does get hammered pretty hard, but there are a lot of fish in it due to stocking. It is worth fishing if you like small streams. I fished private water on the Soque and the fish were HUGE. Problem is, there is no public water to speak of, so you have to know someone or pay out the wazzu.

There is a forum that has a lot of information on North Georgia fishing along with stream reports. I think the link is http://www.georgia-outdoors.com/forum/index.php
