The lagoon is an artificial irrigation reservoir that has evolved into a secondary ecosystem supporting biodiversity.
It is a recognized site for the observation of the Lake Duck (Oxyura vittata) and various species of herons.
The water body acts as a microclimate regulator, noticeably lowering local temperatures compared to the surrounding vineyards.
Geologically, it sits on the transition zone between the Andean foothills and the low-lying plains of eastern Mendoza.
Laguna El Viborón is a natural reservoir located in the Maipú department of Mendoza, serving as a critical wetland area within the arid regional landscape. The site functions as a recreational space for locals and a birdwatching destination due to its proximity to the Mendoza River basin. It features a freshwater lagoon surrounded by riparian vegetation, which contrasts sharply with the surrounding xerophytic environment. The area is managed as a provincial natural reserve, focusing on the preservation of local aquatic ecosystems. It provides a rare habitat for migratory and resident bird species in the Cuyo region.
