Açude Gavião is a reservoir located in Pacatuba, within the metropolitan region of Fortaleza, approximately 30 kilometers (about 45 minutes by car) from the city center. It serves as one of the principal water supply reservoirs for the capital of Ceará. The reservoir has a total storage capacity of approximately 33 million cubic meters, with water depths ranging from 5 to 12 meters on average and reaching a maximum of around 20 meters.

Access to the reservoir is via paved road, and there are multiple points along the shoreline with open margins that allow access to the water. The site has minimal tourist infrastructure, so paddlers should plan to bring all necessary supplies and equipment.

The reservoir is a strategic public water supply source, and any activities on the water are subject to regulation by Cogerh (the state water resources management agency). Fishing is permitted in designated areas with Cogerh authorization, and it is advisable to verify with Cogerh regarding any specific restrictions that may apply to paddling or boating activities before visiting.

The fish community includes tilápia, tucunaré, traíra, and cará, which reflects a warm-water tropical environment. Water temperatures in the reservoir typically range between 26 and 32°C. The period from May to September is the most favorable season for water-based activities, corresponding to the post-rainy season when water levels tend to be higher following the Ceará wet season.

The surrounding landscape is characteristic of the semi-arid northeastern Brazilian interior, with rocky points along the shoreline serving as identifiable features. The reservoir's proximity to Fortaleza makes it a practical destination for a day trip from the capital, though the absence of developed facilities means paddlers should arrive self-sufficient.
