Ghana Water Limited (GWL) has begun a controlled release of excess water from the Weija Dam after water levels rose above safe operating limits, raising concerns about potential overflow.

In a statement issued on May 27, 2026, the utility company said the dam’s water level had exceeded 48 feet, prompting authorities to open all spill gates as a precautionary measure to protect the facility’s structural integrity.

GWL explained that the decision is part of standard safety procedures applied during periods of heavy rainfall, when inflows into the dam increase significantly.

The company stated: “The Management of Ghana Water Limited wishes to inform the public that the water level in the dam has currently risen above the maximum operating level of 48 feet. Consequently, all spill gates of the dam are being opened to allow for the controlled spillage of excess water to safeguard the structural integrity and safety of the dam.”

Officials added that controlled spilling is routinely carried out during the rainy season to reduce pressure on the dam and prevent possible damage or disaster.

“The public may recall that every year during the rainy season, and anytime the water level exceeds 45 feet, Ghana Water Ltd undertakes controlled spilling operations to prevent undue pressure on the dam and avert any potential disaster,” the statement noted.

GWL also warned that further inflows are expected, citing forecasts from the Ghana Meteorological Agency of continued heavy rainfall upstream, which could prolong the spillage period.

“The Ghana Meteorological Agency has forecast further torrential rains upstream, which is expected to result in increased inflows into the dam area,” the statement said, adding that the release may continue for weeks or months depending on rainfall patterns.

Residents along downstream communities have been urged to move away from flood-prone areas as authorities monitor the situation and manage water discharge levels.
