Basalt extraction at the site began in the 1930s. As the town grew, the blasting began to threaten homes and residents, and in 2007, following action by the Public Prosecutor's Office, the authorities forced the mining to end. Once the pumping stopped, the water rose and formed the lake.
The first exploration dives were made in 2012, and the operation returned to the site in 2016. The name comes from the biguás, diving birds that the first divers found living there and that still live at the site.
The lake has three plateaus, which were old mining roads, and on one of them there are cabled items set up for divers. Underwater lie the old quarry's bunkers and abandoned submerged vehicles. There are schools of tilapia in the lake. The bottom is made of very fine particles, and a single touch of a fin stirs up sediment that can take a long time to settle.
