Depth to Watertable (soils)

Depth to watertable mapping highlights land where watertables may be sufficiently shallow on a seasonal basis to affect plant growth. It is intended to describe soil conditions for plant suitability and is not intended to be a literal map of watertable levels, which will change over time. Mapping shows the shallowest depth to watertable observed (provided it accounts for at least 30% of the map unit), while detailed proportion data are supplied for calculating respective areas of each depth to watertable class (spatial data statistics).
