Embalse Los Molinos is a large reservoir in the center-west of Córdoba Province, Argentina, situated at approximately 769 meters above sea level in the Valle de Paravachasca, within the Calamuchita Valley. The reservoir covers a surface area of 24.5 square kilometers, holds around 307–399 million cubic meters of water, and reaches a maximum depth of 57 meters. It is fed by the Río Los Molinos and a number of rivers and creeks descending from the Pampa de Achala, draining a catchment basin of roughly 980 square kilometers.

The lake is well established as a destination for nautical activities, with motorboats, kayaks, sailing boats, and stand-up paddleboards all regularly used on the water. Local operators based at Villa Ciudad de América offer boat rentals, kayak outings, and SUP sessions, making it accessible for paddlers who arrive without their own equipment. The surrounding terrain features undulating hills with both native and introduced vegetation, and the typically clear skies of Córdoba provide good visibility across the water.

The shoreline has formed numerous beaches of varying character and orientation, and several camping areas are available along the margins. Accommodation in the form of cabins, bungalows, and inns is found on the hillsides overlooking the reservoir. The nearby towns of Potrero de Garay and Villa Ciudad de América are the main service centers, while Villa General Belgrano and Alta Gracia are also within reasonable distance. Provincial Route 5 runs along the eastern margin, Route S-495 along the north, and Route S-271 along the west, providing road access from multiple directions. The reservoir is roughly 45 minutes by road from the city of Córdoba.

Fishing is a significant activity on the lake, with pejerrey (silverside) being the primary target species, along with carp and bagre (catfish). Rainbow trout are caught at the mouths of the inflowing streams. Fishing regulations are strict due to past overfishing, and anglers are required to hold a valid license. Catch-and-release fly-fishing is practiced in the area. Paddling is not restricted, though the secondary Compensador La Quintana reservoir nearby prohibits motorized craft while permitting non-motorized paddling and fishing.
