As with other Hunter Region water storages, Lake Liddell can be affected by algal blooms. Algal blooms are seasonal events that result from a combination of particular environmental conditions including nutrient availability, temperature, light intensity, water turbidity and stability.
The NSW Algal Advisory Committee has endorsed interim National Health and Medical Research Council (NHMRC) Recreational Guidelines for algae. The guidelines use a colour alert framework to indicate appropriate recreational use of a water source.
GREEN = Suitable for recreational use
AMBER = Recreational use not recommended
RED = Closed for recreational use and consumption of fish caught from the lake not recommended
Macquarie Generation conducts regular algae testing of Lake Liddell.
