Wetland Types
HGM Class: Riverine
HGM Subclass: Backwater
HGM Class: Mineral Soil Flats

Backwater wetlands are located in areas adjacent to the White Oak Bayou channel. After flooding, water becomes trapped in these backwater wetlands and is prevented from returning to the main channel.

Overbank wetlands occur along natural levees of meandering streams and receive floodwaters coming from upstream which return to the river channel during flood recession.
HGM Subclass: Impounded Riverine
HGM Subclass: River Swamp
