Water Table – Depth

This data layer depicts the depth to the water table. It was developed by the Minnesota Department of Natural Resources. The water table is the upper surface of the subsurface zone that is saturated with water. The depth of the water table below the land's surface was estimated using Natural Resources Conservation Service depth to water table in saturated soils data, surface water elevation, the static water level within certain wells, and a digital elevation model (DEM) of the landscape. The depth to the water table is important for many ecological processes, including vegetation growth patterns, interactions with surface water, and pollutant transport. It is also important for drilling wells for drinking and irrigation water.
