As per latest data, this decline in snow persistence has been consistently observed for three consecutive years.

Seasonal snowmelt is crucial for water availability in the vast stretches drained by the two perennial rivers. It contributes to around 23% of the annual flow, especially in early summer, and nourishes rivers for various purposes including agriculture and hydropower.
