Lakes too becomes seasonal.
This happens during summers, when the sun sets in and the temperature rises due to this rise in temperature several Lakes faces a huge amount of water scarcity which then may lead to the complete evaporation of water causing the Lake to become dry.
But it is all different in the rainy seasons, when due to excess of rainfall Lakes are again replenished with the excess of Rainwater.
