Rockhampton Regional Council has warned local residents to avoid swimming and undertaking any water sports at No.7 Dam at Mount Morgan following the return of high blue green algae levels.
Council says the algal bloom started late last year and while the level 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,” it said in a statement.
Council officers will continue to regularly test and monitor 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,” Council said.
