In an effort to bolster native brook trout population in the area, an eight-mile stretch of Lynn Camp Prong and its tributary Marks Creek is open to rainbow trout fishing. Anglers are allowed to keep all the rainbow trout they catch from June 2 through June 14 from 7:00 a.m. to 7:00 p.m regardless of its size. Park biologist will then re-stock brown trout in the designated area. Anglers are required to check in at the Park Service Station ¼ mile up Middle Prong Trail at the end of Upper Tremont Road.
Rainbow trout were introduced in the late 1880 and are now the dominant trout species in Tennessee.
