TODAY might have been considered black Friday indeed with the temporary closure of Borumba Dam to swimming and waterskiing, because of the presence of blue-green algae (cyanobacteria).
A spokesman for Seqwater said the blue-green algae level was at "red" and once it was out of red, the dam would be reopened.
"The dam will not be closed any longer than it has to be," he said.
"The level is being monitored every couple of days.
"The temporary closure of the dam is a precautionary measure in the interest of public safety."
He said blue-green algae was not something that could be treated because it naturally occurred and dissipated according to weather conditions and was among the earliest-known life forms on earth.
Blue-green algae blooms generally occur in the warmer months of the year due to increased water temperature and optimal light conditions.
Despite blue-green algae's environment benefits, it can also be a nuisance and produces toxins and odorous compounds.
"Signage warning of the closure was erected at the dam yesterday," he said.
