Axia Lowers Colíder Dam Risk Level, Begins Controlled Reservoir Refill

Overview

• The Colíder hydropower plant formally shifted from alert to attention following technical analyses of the dam’s condition.
• Refilling will proceed at a maximum of 25 centimeters per day under continuous monitoring of structural integrity, water quality and fauna, with ongoing community communication.
• Authorities authorized the procedure after evaluating Axia’s action plan and recent test results.
• The August escalation stemmed from damage to 4 of 70 drains and indications of subsoil material migration beneath the dam.
• Earlier reservoir drawdown caused documented fish deaths and local economic losses reported by prosecutors, with oversight continuing as levels rise.
