River in Poland
At the mouth it carries 85 m³/s on average: an Olympic pool every 30 seconds. It drops from 387 m to 166 m, 1.1 m per kilometre on average. Its basin covers 3,528 km², about the size of CV. 1.3 million people live in it. Highest water: from April to May; lowest: from December to February. Dams and reservoirs hold back a large share of its water (18% of a year's flow).

Wisłok, month by month
Highest water: from April to May
Lowest water: from December to February. Freezing months (average below −4 °C): January. Best months to visit: from May to September.
From about 49 m³/s in the lowest month to 170 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.
