This system utilises recorded data captured by Manly Hydraulics Laboratory (MHL) on behalf of Hornsby Shire Council. Recorded data is download at 7 am each morning at all monitoring locations. Displayed salinity values are calculated as the average of salinity measurements for the latest 24 hours of data. At locations without recorded data, salinity is estimated using correlated values from nearby recorded data.

The State of NSW (of which MHL is an agency) does not warrant the quality, accuracy, currency, reliability or correctness of this information and accepts no liability for any loss, injury (including death), or damage which any person relying on this information may suffer.
