Wetland WA/WB is contained within the floodplain of Horse Creek. WA/WB likely receives
hydrology from overbank flooding of Horse Creek and heavy precipitation events.

Remarks:
WA/WB is located in the geomorphic floodplain of Horse Creek. Water-stained leaves and algal
crusts were observed within the lower-elevation depressions. No water table or saturation was
observed.
