The Tangipahoa River channel:

  • Is straight in the upland stream area as it flows south to Highway 190, with a sand and gravel substrate;
  • Becomes a lowland stream with a muddy substrate south of Highway 190.

The stream bank:

  • Has bluffs in the upland areas where the land lies far above the high water of the river;
  • Has sandy beaches or gravel areas in streamside deposits;
  • Has cypress swamps near the point at which the stream enters Lake Pontchartrain;
  • Has lush vegetation, either forest or swampy wetland, lining other areas of the stream bank.

The floodplain:

  • Is composed of pine forest and pasture lands in the upland area;
  • Consists of cypress and tupelo swamp in the lowland area where the stream widens.
