The Dinamarca dam, located in Serra Negra do Norte in the Seridó region of Brazil, started to overflow following significant rainfall in the state of Rio Grande do Norte. The Instituto de Gestão das Águas do RN (Igarn) confirmed that the dam had reached its maximum storage capacity of 2,724,425 cubic meters on Sunday, leading to what is known as 'sangria' or overflow. This event reflects a sharp increase from just 8.3% capacity recorded on February 23 of the same year, which indicates fluctuating water levels due to seasonal rains.

The overflow of the dam is significant as it plays a crucial role in providing public water supply for the local community of Serra Negra do Norte. Last year, the same dam overflowed in January, suggesting that seasonal rains can greatly affect local water availability. The water management institute's alerts and updates highlight the need for careful monitoring of reservoir capacities during periods of heavy rainfall, as such overflow events can impact infrastructure and local resources.

In addition to the Dinamarca dam, the report mentions that over 35 other reservoirs in the region are also experiencing increases in water volume, highlighting a wider pattern of rising water levels across various reservoirs in the area. This spike underscores the importance of maintaining these water sources and preparing for the implications of fluctuating water levels, which can influence both local ecosystems and community needs.
