Ayaguz River, month by month
Highest water: from April to May
Lowest water: from January to March and September. Freezing months (average below −4 °C): from November to March. Melting snow makes up much of its water. Best months to visit: from May to September.
From about 1.0 m³/s in the lowest month to 230 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
