Açude Riacho do Sangue, lac au Brésil
The Açude Riacho do Sangue is a large reservoir built in the city of Solonópole in Ceará state, constructed over the bed of a river with the same name. The structure is made of stone and stretches more than 300 meters in length, with the ability to hold over 61 million cubic meters of water.
Construction began in 1915 during a severe drought and was completed in 1918, when the structure was handed over to local water authorities. The project came from Leopoldo Rodrigues Pinheiro, an engineer from the city, who requested in 1911 that authorities send experts to help build the dam.
The name comes from an old local story tied to the founding of the river that feeds it. You can see how important this reservoir is to the community when you visit, as locals regularly come to use its water or simply spend time by its banks.
The structure is located near downtown Solonópole and is easily accessible to visitors wanting to explore the site. The best time to visit is after the rainy season, when water levels are high and you can see the reservoir at its fullest.
The structure experienced its first overflow in 1917, a year before its official inauguration, flooding nearby streets. In the 1960s, the reservoir had to be emptied to combat dangerous piranhas, which were removed using a natural powder called Timbó.
