Mostly annual sites with very few “open” for camping travelers and even fewer with full hookups. Water/Electric mostly as the sites with sewer hookups are mostly annuals or “tiny homes” built on the sites with full gravel drives and residential propane. If you are an RVer passing thru for a night or two that’s great, but planning any sort of week(s) long trip on the lake is luck based despite what you site type you signed up for.
Beautiful lake park in Lake Gaston, but totally an annual playground with few available sites for full hook up RVs
