The velocity of groundwater is usually measured in mm/day, week or month, depending on the permeability of the ground in question. The whole business of dowsing depends upon the idea that water travels underground in streams, like those seen in limestone caverns, which is not usually the case. Groundwater inhabits the ground in the same way that water can occupy a sponge; by filling up the interstices, or voids between grains. One can drill down to get groundwater anywhere; the only factor which is open to variation is the permeability of the rock or soil at the particular location. A highly permeable sandstone will release water more quickly than a granite. A highly fractured zone in a rock will be more permeable than one lacking fractures. Where the surface of the ground is below the water table we get ponds, lakes, rivers and the sea.
