Lago Paranoá is an artificial reservoir located within the urban fabric of Brasília, in the Federal District of Brazil. Created by damming the Rio Paranoá, the lake was conceived as an integral element of the new capital's design from the outset and has become one of the city's defining geographical features. Its coordinates place it at approximately 15°47'S, 47°48'W, and it sits within a landscape of cerrado vegetation, red-earth cliffs, and eucalyptus groves along portions of its shoreline.

The lake supports a wide range of paddle sports, including kayaking, canoeing, and stand-up paddleboarding. A notable route is the Paranoá–Gama kayak route, rated as moderate in difficulty and considered well-suited for rowing sports. Speedboats are active on the water, particularly on weekends when the lake sees heavy recreational use, so paddlers should be prepared for wake and boat traffic. Speedboats frequently drench other water users, making dry bags advisable even for casual outings.

The best conditions for paddling tend to fall between April and June, when temperatures hover around 26°C, the air is dry, and winds are generally calm. July mornings can produce mist rising off the water, with nighttime temperatures dropping to around 12°C. December brings storms capable of generating whitecaps that can cancel paddling excursions entirely. Weekday afternoons, particularly midweek, see significantly less traffic than Sunday mornings, when the lakeside paths and water fill with recreational users.

Three islands are present on the lake — Paranoá, Retiro, and Clubes. Paranoá and Retiro islands are designated ecological reserves under District Law no. 1,612 of August 8, 1997. Clubes Island is the smallest, measuring approximately 6 square meters, and sits near the Juscelino Kubitschek Bridge. The lake also contains a submerged village, which is a recognized dive site, though this requires certification and a guided tour operator.

Common fish species in the lake include redbreast tilapia, monoculus peacock bass, and black pacu. Access to the lake itself is generally free and public, though outfitters and clubs along the shore offer rentals and organized paddle excursions. The Lago Norte shoreline has a lakeside cycling and pedestrian path that runs alongside the water, providing context for paddlers navigating that section of the lake.
