Chefna

Chefna is a river of Belgium.
It springs in Ville-au-bois and flows for 5 kilometres through the province of Liège, before emptying into the Amblève.

Around 1802, several farmers started looking for gold in the river and on the right bank the pits of a primitive goldmine can be found, although they have been mostly overgrown. The river had a low yield of about 0.40 grams of gold per ton of rock, although locals still talk about the man who "almost became a millionnaire" at the end of the 19th century.
