Here’s a lake in Portugal that funnels into a huge drain-like waterfall

At the Conchos Dam in Portugal, visitors are treated to an amazing sight during flood season. As the dam overflows, water is drained into a funnel-like waterfall within the artificial lake.

Named Covão do Conchos, the strange almost otherworldly cascading cavity is an example of a “bell-mouth spillway.” A spillway is a type of a structure within a dam used to divert water to a downstream area. In this case, a 1.5km tunnel, so that the water doesn’t spill over the top of the dam and damage it.

The water doesn’t usually flow into the spillway except during flood periods, meaning this spectacle is only around for a short time every year.

So if you’re ever in Portugal, make sure to add this swirly sight to your list.
