IMBIL tourist magnet, Lake Borumba is temporarily closed to skiing and jet skiing after an outbreak of toxic blue-green algae, authorities have announced.
The lake's operating authority, SEQWater announced the closure this morning, but said the lake remains open for fuel powered craft, fishing and paddling.
But swimming is out, for the time being, due to safety concerns linked to the dangers of health effects from ingesting the single celled algae, technically known as cyanobacteria, or from contact with eyes and with cuts or abrasions.
Blue-green algae blooms generally occur in the warmer months due to increased water temperature, abundant nutrients and optimal light conditions.
Seqwater is closely monitoring algae levels and will re-open the lake when water quality results indicate it is appropriate to do so, a spokesman said.
