Research notes
Roughly 50+ designated Scenic Rivers across the state including the Amite, Bogue Chitto, Tchefuncte, Tangipahoa, Bayou Bartholomew, Whisky Chitto, Vermilion (portions), Pearl River tributaries, and many headwater streams. Permits issued by LDWF (not LDENR). Concurrent with — does not preempt — local zoning, but functions as a parallel approval gate. Use is restricted within the channel and immediate corridor; floodplain regulation upstream/downstream is separately governed by NFIP/floodplain ordinances.
