Yes, I catch more in the warmer water as well. I fish the river from NC down to Cola and its all good. If you ever need more content on specifically rivers, there is a good website for SC rivers with a message board too. Here is the link.

Or, just go straight to the SC site here. There is a good article on the home page about the Broad river that I wrote.

Good to see some more river discussion going on around here. Those smallies are fun fish to catch. If you are into kayak, canoe or wade fishing rivers then you'll like the SC river fishing website.
