Perched water table means a saturated soil horizon or horizon subdivision, with a free water surface periodically observed in a bore hole or shallow monitoring well, but generally above the normal water table, or may be as identified by drainage mottles or redoximorphic features, and caused by a less permeable lower horizon.
Perched water table means a saturated zone, generally above the natural water table, as identified by drainage mottles caused by a restrictive horizon.

Perched water table means water, surface and/or subsurface, which accumulates on or in the upper strata of soil or subsoil due to an impervious layer beneath.
Perched water table means the soil is saturated with water in one or more layers within 200 centimeters of the mineral soil surface and has one or more unsaturated layers with an upper boundary above 200 centimeters in depth below the saturated layer. The zone of saturation , i.e. the water table is perched on top of a relatively impermeable layer. The Natural Resources Conservation Service also classifies this as epi-saturation.
