State Park is pretty large and there are a number of different areas to stay in over there. There are a couple different channels that Taylor is talking about (one being Cole Campground) but a good part actually fronts the main lake. Lots of great fishing in that area throughout the year. I've only stayed a couple times and they have nice facilities (hot showers, nice launch ramp, large parking lot, rv spaces, etc) and is well kept up.

Hopefully more will post some additional information.
