Surface-water stage, ground-water elevations, rainfall, and streamflow were monitored at or near four wetland sites at Arnold Air Force Base, Tennessee. Two of the wetland sites (Sinking Pond and Westall Swamp) included sinkholes with internal relief greater than 7 feet. The other two wetlands (Tupelo Swamp and Goose Pond) were shallow depressions with less than 5 feet internal relief. Stage rose and fell abruptly in the two sinkhole wetlands. Water depths ranged from 0 to 11.4 feet in Sinking Pond and from 0 to 8.5 feet in Westall Swamp. Water levels in wells adjacent to the sinkhole wetlands also rose and fell abruptly. The two shallow depressions filled and drained more gradually and remained flooded longer than the sinkhole wetlands. The maximum recorded water depths were 3.5 feet in Tupelo Swamp and 2.3 feet in Goose Pond. Water levels in nearby wells remained lower than surface-water elevations in the shallow depressions throughout the study period.
