River in Poland and Belarus, tributary of the Vistula river
At the mouth it carries 320 m³/s on average: an Olympic pool every 7.8 seconds. It drops from 157 m to 67 m, 0.2 m per kilometre on average. Its basin covers 75,200 km², about the size of PA. 5.5 million people live in it. Highest water: from April to May; lowest: from January to February. No large dam holds it back: it is one of the world's free-flowing rivers.

Narew, month by month
Highest water: from April to May
Lowest water: from January to February. Freezing months (average below −4 °C): from January to February. Best months to visit: from May to September.
From about 210 m³/s in the lowest month to 670 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.
