Not more than ten trout may be taken from the freshwater streams of the State in any one day except for that portion of Matthews Creek and Middle Saluda River which lies in Greenville County, Eastatoe River in Pickens County, Whitewater River in Oconee County, and Lake Jocassee in Oconee and Pickens Counties. The department may promulgate regulations to establish creel and possession limits, bait limitations, and for any other purposes to protect the trout fishery. As used in this section the word "trout" means rainbow, brook, brown, or other species of cold-water trout and does not mean freshwater bass.
