Ghana Water Limited (GWL) has commenced a controlled spillage of excess water from the Weija Dam after levels rose above the facility’s maximum operating threshold, raising concerns about potential downstream flooding.
In a statement issued on Thursday, management said the dam’s water level has exceeded 48 feet, necessitating the opening of all spill gates to relieve pressure and protect the structural integrity of the facility.
The move, officials explained, forms part of routine safety protocols implemented during peak rainy seasons.
“Anytime the water level exceeds 45 feet, controlled spilling becomes necessary to prevent undue strain on the dam and avert possible disaster,” the statement noted.
The latest development comes amid forecasts of continued torrential rainfall in upstream catchment areas.
According to Ghana Water Limited, the Ghana Meteorological Agency has projected sustained inflows into the dam, a situation expected to prolong the spillage exercise.
“This process may continue for some months depending on rainfall patterns and inflow volumes,” the company cautioned, indicating that the situation remains dynamic.
The Weija Dam, a critical water supply infrastructure serving large parts of Accra and surrounding communities, has historically required controlled spillages during periods of intense rainfall to maintain safe operating levels.
GWL has issued an urgent advisory to residents living along the river downstream of the dam, warning them to evacuate vulnerable areas without delay.
“All persons living along the course of the river are strongly advised to move immediately to forestall any eventuality and ensure the safety of lives and property,” the statement emphasized.
Flooding risks in downstream communities have been a recurring concern whenever spillages are undertaken, with past events leading to displacement, property damage, and disruptions to livelihoods.
The National Disaster Management Organisation (NADMO), in collaboration with various Metropolitan, Municipal and District Assemblies, has reportedly begun preparations to mitigate the anticipated impact.
Authorities are planning to remove structures and clear obstructions along water channels to ensure the free flow of excess water into the sea.
GWL has urged swift action on these measures.
“We call on relevant authorities to undertake these interventions as early as practicable to minimize flooding risks and protect affected communities,” the company said.
Ghana Water Limited reiterated its commitment to safeguarding both the dam infrastructure and public safety but stressed that cooperation from residents and institutions will be vital in managing the situation.
Emergency directives and advisories issued by state agencies, it said, must be strictly adhered to in order to reduce the risk of casualties and damage.
Residents are also being encouraged to stay informed through official channels and avoid areas prone to flooding during the spillage period.
