Title: Blue - Green Algal Monitoring - Hawkesbury River
Custodian: Environment Protection Authority NSW
Jurisdiction: New South Wales
Sydney Water and EPA algal counts for up to seven sites on the Hawkesbury River from Windsor Bridge to near Wiseman's Ferry since September 1992. Sampling usually on weekly basis. Two species of algae (Anabaena circinalis and Microcystis sp.) are monitored, recording toxicity and calculated counts for a volume of 1 mL.

Geographic bounding box:
The bounding box encloses the maximum extents of the dataset. There may be voids or gaps within the bounding box, depending on the defined coverage of the dataset. Outer bounding rectangle as Latitude/Longitude coordinates based on the WGS84 datum (expressed as both Degrees Minutes Seconds and as decimal Degrees):
- North bounding latitude: 33 22 30.0 S (-33.375)
- South bounding latitude: 33 37 30.0 S (-33.625)
- East bounding longitude: 151 00 00.0 E (151)
- West bounding longitude: 150 45 00.0 E (150.75)
