Surface Water Ambient Network (SWAN) – Water quality

HIDE THIS SECTION

Coverage

January 1960

Ongoing

The program aims to:

• Collect information to assist the management and assessment of Queensland’s surfacewater resources
• Collect ambient water quality data (over a range of flow conditions) at a selection of stream gauging stations to enable the assessment and reporting condition of condition and trend of Queensland’s freshwater aquatic ecosystem health.

Partner organisations

Queensland Health Forensic and Scientific Services (notional program for analysis of manual samples)

In-situ (on-site) sampling at all sites may include:

• Electrical conductivity at 25º C
• pH at 25º C
• Temperature

Continuous time series measurements at a subset of sites:

• Electrical conductivity at 25º C
• pH at 25º C
• Temperature

Statewide

The Surfacewater Ambient Network and consists of 242 stream gauging station sites in Queensland.

Monitoring frequency is defined in the approved network list and is variable.
