a mud table
The area immediately below the water table is called the zone of saturation. This zone is where spaces between soil and rock particles are filled with water. Groundwater is found in this zone and can be extracted through wells.
If it is below the water table, it is an aquifer. Otherwise I think it is just called an underground resevoir.
The level below which the soil is saturated is called the water table. This is the level at which the soil and rock are saturated with water and below which the spaces between soil particles are filled with water.
A hole dug below the water table that fills with groundwater is called a well. Wells are typically constructed to access natural underground water sources for various purposes like drinking water supply or irrigation.
A hole dug below the water table that water seeps into is called a well. Wells are constructed to access groundwater for various uses such as drinking water supply, irrigation, and industrial purposes.
When the level of land drops below the water table, it forms a depression called a groundwater basin. This basin becomes saturated with water and can lead to the formation of a lake or wetland.
The bedrock below an aquifer is called the water table. For example if a hole is dug into sand, very wet and saturated sand at shallow depth this would represent the aquifer and the level to which the water rises in this hole would be called the water table.
The layer of rocks and soil above the water table that are usually not filled with water is called the unsaturated zone or vadose zone. This area allows water to percolate down to the groundwater below.

water table
The water table is the level below the ground where all spaces are filled with water. Wells are structures dug or drilled into the ground to access the water below the water table. The depth of a well is determined by the distance between the water table and the surface.
