The Goriaux pond (former pig pond as its dialect name indicates) is a mining subsidence pond in the North, in France, and a national biological reserve since 1982. A very significant mining subsidence created three ponds in 1916, which ended up joining around 1930 to form a single pond, located at the foot of slag heap no. 171, Mare à Goriaux, partly recolonized by vegetation. The site of the body of water and the slag heap of the pond in Goriaux is part of the Raismes-Saint-Amand-Wallers national forest.

Nice spot, possibility to land, soak your feet in the water. Not far from the Arenberg gap. Accessible slag heap along the Mate in Goriaux which gives a view from above. Be careful, very narrow and sloping path if you want to go along the pond on the slag side.
