Lagoa Do Nazaré is located near the city of Nazaré do Piauí, approximately 210 km from Teresina in the sertão (semi-arid interior) of Piauí state. The lake serves as one of the state's recognized natural landmarks and draws visitors for its scenic qualities amid the surrounding dry landscape.

Boat trips on the lagoa typically run around 30 minutes, giving a sense of the lake's modest size. The water is used locally for swimming and fishing, with the fishing community representing a longstanding presence on the water. Stingrays inhabit the lagoa, which is a relevant safety consideration for anyone entering the water or launching from shallow shoreline areas.

The hydrology of the lake is closely tied to the region's irregular rainfall patterns. The lagoa dried up completely in 2012 during an extended drought period, significantly impacting local fishing and agriculture. Rainfall in 2015 refilled the lake, and as of around 2020, water levels had been maintained at roughly one meter for approximately four years. Paddlers planning a visit should be aware that water availability is subject to the region's variable precipitation, and the lake's condition can change substantially between dry and wet years. The rainy season is the more reliable period for adequate water levels.

The surrounding environment reflects the sertão landscape, and the lake functions as a focal point for the local community of Nazaré do Piauí.
