History
[edit]
In 1777 Martinho Coelho and Gustavo- Mauricio Silva De Carvalho Alves discovered the hot water springs that became known as Caldas de Piratinga, later changing the name to Caldas, on the banks of the Caldas River. The discover registered the land and established a ranch on the left bank of the river, which he named "Fazenda das Caldas". Gold was found in small quantities attracting prospectors and others in search of cures in the hot waters. In 1850 another settlement arose on the right bank of the river near the hot springs, where a church was soon built. In 1857 Caldas Novas became a district and in 1911 it became a municipality.

Almost two thousand people are employed in this sector. The infrastructure of the city has more than 80 hotels and pensions (12,000 beds), (many with heated swimming pools and all with hot water produced by the natural thermal system), chalets, clubs, nightclubs, bars and restaurants.

Information about the hot water of Caldas Novas
[edit]
In Caldas Novas there are 86 active wells, pumping an average of 1,200 m3 an hour, in a period of 14 daily hours. The temperature of the water varies between 34 and 57 °C.
The first references to the hot water of this region were published in Spain in 1545. In 1722, Bartolomeu Bueno da Silva, son of the famous bandeirante, Anhangüera, turning off the trail blazed by his father years before, discovered the thermal springs that form the Rio Quente. These were called Caldas Velhas and were located in the place where the Rio Quente Resorts is now located.
The most important study about the thermal ism of Caldas Novas and the Rio Quente was carried out by the state enterprise Furnas Centrais Elétricas, due to the possible influence of the Usina Hidrelétrica Corumbá I dam on the thermal water table of the region, which would be under the risk of cooling. According to Furnas, the phenomenon of the hot water is produced by peculiar geological and topographic characteristics. For years it was thought that a volcano had existed in the area in whose crater rainwater infiltrated, heating at great depths and then returning to the surface by way of cracks in the rock. More modern studies show that there is no indication of volcanic activity in the region.
Studies show that the water is formed by rainfall that is stored in a layer of quartzite and due to pressure is sent to the surface in a column 600 meters.
The suspicion that the cold water of the reservoir of Usina Corumbá I could infiltrate the thermal watertable of Caldas Novas and Rio Quente has no basis, since the waters of the lake are at an elevation of 595 meters, well below the source of the water, at 644 meters.
The municipality contains part of the 12,315-hectare (30,430-acre) Caldas Novas State Park which protects the Serra de Caldas plateau region that is the main source of water for the geothermal aquifers of the region.
Ecotourism is also present at Caldas Novas as the city is located near the Corumbá River and the Caldas Novas State Park. In the surrounding area there is a lake - Lago de Piratininga - with boiling water; a reservoir called Lago de Corumbá with 64 square kilometers damming the Corumbá; and another river - the Rio Quente - which has natural warm water.
Rio Quente
[edit]
One of the largest hotwater resort complexes in the world - Rio Quente Resorts - is located 20 kilometers to the west of Caldas in the municipality of Rio Quente. With seven hotels, a convention center, and 500 square kilometres of space it receives more than 1 million tourists a year.
