The water levels of the Indus River fluctuate significantly throughout the year due to its reliance on snowmelt and seasonal rainfall.1

Lowest Water Levels: The river reaches its minimum discharge during the winter months, specifically from mid-December to mid-February.1
Highest Water Levels: The river experiences its maximum water levels during the rainy season, typically occurring between mid-July and mid-August.1

Following the winter minimum, the river begins to rise in the spring and early summer (March to June) as snowmelt increases, before reaching its peak during the monsoon-influenced flood season from July to September. After mid-August, the water level falls rapidly until the beginning of October, when it begins to subside more gradually.1
