Embalse Collagasta, also known as Dique Collagasta, is a reservoir located in Catamarca, Argentina, approximately 9 kilometers southeast of the town of La Villa de El Alto. The reservoir's primary function is water storage, creating a significant body of water in the arid regional landscape. For paddlers, the water body is accessible for activities like canoeing and boating, as indicated by user-shared GPS tracks and routes. A specific paddling track recorded in October 2023 details a trip lasting approximately 5 hours and 53 minutes of total time, with 2 hours and 12 minutes of active movement, suggesting a route suitable for a half-day excursion. The reservoir is also noted as a destination for fishing, which implies the presence of boat ramps or other access points for launching small craft. The surrounding area is characterized by its proximity to the town of El Alto and the broader, mountainous terrain of Catamarca province. Given the climate of the region, the best seasons for paddling are likely during the warmer, drier months, with autumn (around October) being a documented time for activity.
