About this water

The Castanhão Dam is a dam in the state of Ceará, Brazil. It is the largest multiple use reservoir in the country, the largest on an intermittent river, and the main reservoir for the state and the metropolitan region of Fortaleza. The dam supplies drinking water, and supports industry, irrigation and fish farming. Through steady release of water the dam maintains water flow in the Jaguaribe River throughout the year. During 2012–16 Ceará experienced a prolonged drought. Water levels in the reservoir dropped to 5% of capacity and usage had to be rationed.
