Ghana Water Limited (GWL) opened the spill gates of the Weija Dam on May 28, 2026. This action led to widespread flooding in downstream communities. Tetegu, Sampah Valley, and Choice communities are among those most affected. Water levels rose significantly, submerging homes and roads.
The spillage became necessary because the dam's water level exceeded its maximum operating capacity. This limit is set at 48 feet. Releasing excess water prevents structural damage to the dam facility. Residents scrambled to save belongings as water levels climbed. GWL confirmed that all spill gates were opened to reduce pressure on the dam.
This controlled spillage is a common yearly event for GWL during the rainy season. It usually begins when water levels reach 45 feet. The Ghana Meteorological Agency predicts more heavy rainfall upstream. This forecast suggests continued high inflows into the dam. The spilling operation will continue until water levels return to a safe operating range.
GWL issued a statement emphasizing the need to safeguard the dam. "The water level in the dam has currently risen above the maximum operating level of 48 feet," the statement read. "Consequently, all spill gates of the dam are being opened to allow for the controlled spillage of excess water in order to safeguard the structural integrity and safety of the dam.". The company urged all residents in vulnerable areas downstream to evacuate immediately.
The implications for affected communities are dire. Thousands of residents are displaced or at risk. Calls for urgent humanitarian aid, including temporary shelter and relief items, are growing. The National Disaster Management Organisation (NADMO) is coordinating efforts. They are working with district assemblies to remove obstacles blocking water flow to the sea. This perennial flooding highlights the need for improved drainage and urban planning in Accra.
