Folasade Akinrinmola, the chairman of the council and the state police command confirmed the incident to journalists on Thursday.
Mr. Akinrinmola said the incident which occurred on Wednesday night involved a team of seven contractors employed by the World Bank on an assessment mission to the dam.
She said the team commenced work on Tuesday night from a section of the dam and that the incident happened when they moved to the other section on Wednesday.
She said the traditional ruler of Egbe notified her of the incident.
“We immediately mobilised a rescue team and an ambulance, and in the process, those wearing life jackets were rescued.
“The rescued people were the ones who told us that others were in the water.
“The bodies of those that had drowned were later retrieved by the local fishermen.”
“One of the dead victims was said to be the son of the leader of the team who providentially escaped unhurt.
“We believe that they came to Ekiti based on some of the proposals we had written on the dam on how it can be put to use.
“We believe that the World Bank has started work on the dam based on their findings,” she said.
The council boss, who described the incident as sad and unfortunate , added that the bodies of the dead had since been deposited at the mortuary in Ode-Ekiti, the headquarters of the council area.
Alberto Adeyemi, the Police Public Relations Officer (PPRO) of the Ekiti State Police Command, also confirmed the incident.
“It is true that the boat transporting the team capsized, four of them died while three survived,” Mr. Adeyemi, a deputy superintendent of police, said.
