Bayou Lacombe

About

From Lacombe through fifteen miles of cypress tunnel to Highway 190, Bayou Lacombe winds through St. Tammany Parish at roughly 120 CFS — a black-water stream that opens into salt marsh as it approaches Lake Pontchartrain. The upper reach stays narrow under dense cypress canopy, while the lower fifteen miles from Highway 190 to the lake pass through Big Branch Marsh National Wildlife Refuge, established in 1994. This is Choctaw homeland within the Lake Pontchartrain Basin, and the bayou still carries the tidal influence and brackish edge that shaped those early settlements. At Class I throughout its 30-mile length, Bayou Lacombe runs best between 50–300 CFS, though no USGS gauge monitors this system. Bayou Lacombe Paddle Shop provides outfitting for those wanting guided access to the refuge waters, where alligators and wading birds replace the cypress swamp wildlife of the upper reaches.
