Algal bloom in Lake Salto Grande, Argentina
Location: Argentina

This Copernicus Sentinel-2 image, acquired on 1 February 2025, shows an algal bloom in the Salto Grande reservoir, at the border between Argentina and Uruguay.

In early February 2025, Lake Salto Grande was affected by a surge in algae growth. This phenomenon has affected local fauna, including capybaras, which have been observed with their fur turned green by the algae.

The Copernicus Sentinel satellites are useful for monitoring the health of water bodies around the world. Furthermore, the Copernicus Marine Service delivers value-added information to support decision-makers in developing effective policies for addressing the consequences of algal blooms, helping to protect communities, preserve ecosystems, and safeguard economies.
