"A subsurface dyke is a structure that is built in an aquifer with the intention of obstructing the natural flow of ground water, thereby raising the ground water level and increasing the amount of water stored in the aquifer. Acting as an underground barrier impermeable to water, it controls the groundwater flow in an aquifer and raises the water table."@en . . . . .
