Blue Green Algae levels high at No.7 Dam

Published on 13 March 2023

Blue Green Algae levels have returned to high in the No. 7 Dam at Mount Morgan and Council is asking residents to continue to avoid swimming and undertaking any water sports at the dam until further notice.

The algal bloom started late last year and while the levels had dropped to medium at the last two reads, recent testing has shown that it is high once again.

Algal bloom is not an unusual occurrence. Decomposing vegetation combined with inflows from surrounding catchments have increased the nutrient density of the water, resulting in this latest algal bloom.

Council officers will continue regularly testing and monitoring the situation.

Rockhampton Regional Council is committed to the safety of Mount Morgan residents and will notify the community when it is safe to recommence activities in the dam.
