Therefore, Conchos sinkhole is a result of human engineering. When you see the water swirling, it seems like it goes to the center of the earth. However, the explanation is much simpler. The water goes through the funnel.

The funnel, in turn, serves the role of water diversion from Ribeira das Naves to Lagoa Comprida. Thus, this sinkhole supplies the nearby communities  with fresh water. However, because of absence of other constructons around, it seems like the sinkhole is a natural wonder, but not the part of a dam system.
