DRAINAGE AND PERMEABILITY: Tyden soils are very poorly drained. Runoff is negligible. These soils remain ponded from December to April. An apparent water table exists from the surface to a depth of 203 cm (80 in) during the fall through spring months.

USE AND VEGETATION: Primarily used for woodland and wildlife habitat. Native vegetation includes water oak, large gallberry, titi, buttonbush, and sweetbay.

DISTRIBUTION AND EXTENT: Southeast Texas; LRR-T; MLRA-152B (Western Gulf Coast Flatwoods; small extent.
