Ecosystems Artificial Opening of the Garzón Lagoon Sandbar 11/21/2025 Share The Ministry of Environment has authorized the artificial opening of the Garzón Lagoon sandbar (Maldonado-Rocha), which will take place between Saturday, November 22nd and Tuesday, November 25th, due to the presence of a cyanobacteria bloom across much of its surface. The opening is being carried out under the monitoring of protected area personnel and technicians from the National Directorates of Biodiversity and Ecosystem Services (Dinabise) and Environmental Quality and Assessment (Dinacea) of the Ministry of Environment, following guidelines, recommendations, and taking into account the best weather conditions to ensure its effectiveness. Technical reports from the Ministry indicate that the cyanobacteria bloom is likely to persist and increase due to weather conditions, making the artificial opening of the sandbar necessary. This action aims to drain water into the sea, carrying nutrients from the lagoon and allowing the inflow of saltwater from the ocean. The openings in the sandbars connect the lagoon water to the sea, allowing the lagoons to discharge freshwater and sediments, and seawater to enter, generating nutrient exchange and increased salinity. Prior to beginning work on this discharge, the various stakeholders involved and represented on the Specific Advisory Commission (CAE) of the Laguna Garzón protected area were informed.
