Ngwu Spring Natural Water Imo State

Ngwu Spring Natural Water: Otherwise known as Iyi Umugara, this natural spring, which is found in Nkwere local government area of the state presents sparkling natural water, pure and crystal-like. It could not exactly be called a waterfall because it lacks the height of one.

The stream is formed by cascading spring water seen as awesome and mysterious given the fact that even during the dry season the flow rather than cease, increases and flows endlessly. Naturally other rivers and lakes would record a drop in volume of its water during the dry season when it sees a depletion of its supply from the natural sources of rain.

A spring may be the result of karst topography where surface water has infiltrated the Earth's surface (recharge area), becoming part of the area groundwater. The groundwater then travels through a network of cracks and fissure—openings ranging from intergranular spaces to large caves. The water eventually emerges from below the surface in the form of a karst spring.



The forcing of the spring to the surface can be the result of a confined aquifer in which the recharge area of the spring water table rests at a higher elevation than that of the outlet. Spring water forced to the surface by elevated sources is artesian wells. This is possible even if the outlet is in the form of a 300-foot-deep (91 m) cave. In this case the cave is used like a hose by the higher elevated recharge area of groundwater to exit through the lower elevation opening.

Non-artesian springs may simply flow from a higher elevation through the earth to a lower elevation and exit in the form of a spring, using the ground like a drainage pipe.

Still other springs are the result of pressure from an underground source in the earth, in the form of volcanic activity. The result can be water at elevated temperature such as a hot spring.
