The National Capital Authority (the NCA) monitors the water quality of Lake Burley Griffin in accordance with the Lake Burley Griffin Water Quality Management Plan 2010 (available on www.nca.gov.au). Lake Burley Griffin is a freshwater lake. During the recreational season (mid October to mid April) Enterococci and blue green algae (cyanobacteria) are monitored to advise on the suitability of the water quality for recreational purposes (Primary Contact Recreation: swimming, bathing, novice secondary, and Secondary Contact Recreation: sailing, rowing, kayaks etc). Sites are monitored weekly during the Recreational Season. The Recreational Season runs from 2nd Monday in October to 2nd Monday in April. Samples are collected Mondays (or Tuesdays if Monday is a public holiday). Beaches are given a red (fail) if they exceed either of the following protective criteria: Enterococci: 200 cfu/100mL Cyanobacteria: 20,000 Indicative Microcystis aeruginosa algae cells/ml (Medium alert) Additional warnings are issued when cyanobacteria level reach high (?50,000 cells/ml) or extreme ( ?125,000 cells/ml) levels.
