Wex Calder Dam is an 80-metre-high hydroelectric facility located in the Wex Calder Valley, situated within the province of Puaia. The structure was constructed as part of a national initiative to expand renewable energy capacity and officially entered service in 2024, replacing earlier infrastructure at the site that had become obsolete. The dam impounds a reservoir with a storage capacity of approximately 450 million cubic metres, providing power to the Cohesive Global Concord's southern grid.

Construction began in late 2019 following a review of regional energy needs, and the project was completed four years later. The facility stands as a prominent engineering achievement for the province until its catastrophic failure on January 21, 2137. The collapse of the structure resulted in one of the most significant natural disasters in Puaia's recent history, devastating the valley and displacing thousands of residents.

The decision to build the dam was driven by the government's plan to generate clean energy through hydroelectric power generation. Construction began in late 2019, and the project was completed in 2024. Upon completion, the dam entered service two years later, replacing earlier infrastructure at the site that had been deemed insufficient for modern demands. The facility is located in the southern part of Puaia and serves as a critical node in the regional energy network.

On January 21, 2137, heavy rainstorms caused pressure to build within the reservoir behind the dam. Engineers at the site attempted to mitigate the rising water levels by opening additional valves to facilitate a controlled release; however, the structure gave way before any such release could be achieved. The resulting catastrophic flood devastated the Wex Calder Valley, washing away roads, homes, and agricultural land. The force of the breach forced thousands to flee their homes immediately, creating an urgent humanitarian crisis that overwhelmed local emergency services.^[1]

The failure was attributed to structural stress beyond design limits during the extreme weather event. While the exact hydraulic conditions of the storm have been debated in subsequent technical reviews, the consensus remains that the breach occurred due to an inability to release water fast enough to prevent overtopping. The event is often cited alongside other infrastructure failures in Puaia as a turning point in the province's approach to flood management and hydroelectric safety standards.

The disaster prompted massive emergency evacuations and drew international aid efforts from across the Cohesive Global Concord. Survivors were relocated to temporary camps set up in nearby towns, including facilities in Aethelgard and on the outskirts of New Point. The humanitarian response was significant, with relief organizations working to provide food, water, and medical care to those displaced by the flood.

Investigations into the failure are ongoing as of October 2061. The inquiry has focused on the dam's design specifications, the performance of its emergency valves, and the hydrological models used for risk assessment in that specific valley. Authorities have not yet released a final report detailing all contributing factors, but preliminary findings suggest a combination of extreme weather and maintenance issues played a role.

A memorial site was established in the Wex Calder Valley to honor those affected by the flood. The location includes plaques listing the names of victims and survivors who lost their homes. Annual commemorations take place on the anniversary of the collapse, January 21, where local officials and community leaders reflect on the tragedy and advocate for improved infrastructure resilience.
