Watercourse in British Columbia and Yukon in Canada
At the mouth it carries 300 m³/s on average: an Olympic pool every 8.3 seconds. It drops from 1,410 m to 592 m, 1.3 m per kilometre on average. Its basin covers 35,500 km², about the size of TW. 28,000 people live in it. Highest water, with the snowmelt: from May to July; lowest: from January to April. No large dam holds it back: it is one of the world's free-flowing rivers.

Teslin River, month by month
Highest water: from May to July
Lowest water: from January to April. Freezing months (average below −4 °C): from November to March. Melting snow makes up much of its water. Best months to visit: July.
From about 150 m³/s in the lowest month to 730 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.
