         Generally Vinayaka Chathurthi is celebrated during the month of August or September just before the setting of Northeast monsoon in October.         The dry summer would have made water sources porous and rivers might have been running shallowly. Thus the clay from the idols when suspended in water would form a colloid that would coagulate the pores and form a layer that has very fine pores.         Water would find it difficult to move towards gravity in such a condition and thus sort to lateral imbibitions. This would naturally lead to increase and rise in the ground water level on the setting up of the monsoon. Our ancestors approached everything with a scientific knowledge.
