What is the depth of the River Dordogne in France?

Question

My dad went canoeing on the Dordogne near Bergerac and said he could see the bottom and that the average depth was only 3' (1m)

Not that I doubt my dad, but that seems strange for such a long, wide river.

The same question applies to the rivers Lot and Garonne in the South West of France

Answer 1

The river arises on the flanks of Puy de Sancy in the mountains of Auvergne and flows west for 300miles before it joins the Gironde river, Bergerac is about 50 miles from the mouth of the river and is shallow in places especially in the gorges or steep valleys. In places the river can be 20 feet or more deep.
