Represa Cachoeira da França is a reservoir located in Juquitiba, in the state of São Paulo, formed by a dam that stands 10 meters high and 200 meters in length. The reservoir is part of the Sistema Produtor São Lourenço, operated by Sabesp, and contributes up to 4,700 liters per second to the water supply of part of Greater São Paulo. Despite its role as water infrastructure, it has developed into a notable recreational destination in the region.

The reservoir is surrounded by Atlantic Forest vegetation, which lines its margins and provides a visually distinctive backdrop for paddlers. Kayaking is among the activities practiced on the water, alongside boat tours, jet skiing, and motorized craft — paddlers should be aware that motorized vessels share the water, which may affect the experience depending on traffic levels.

The fishery is well established, with species including tilápia, traíra, pacu, and tucunaré present in the water. Fishing from kayaks is a common practice here, and the reservoir attracts sport fishing visitors regularly. The presence of submerged and marginal vegetation, typical of tucunaré habitat, is a notable feature of the water body's character.

The reservoir is considered one of the more scenic in the state of São Paulo, with the surrounding Atlantic Forest contributing to its natural appeal. Its proximity to the city of São Paulo makes it a frequently visited destination, and it ranks among the top attractions in Juquitiba. Accommodation and tourism infrastructure exist in the area, and local operators offer guided tours and reservations for activities on and around the reservoir. The town of Juquitiba serves as the primary base for access, with the reservoir reachable from the municipal area.
