Site Alerts

Monitoring sites with active alerts appear in the alert box. Site indicators flash RED if in flood or YELLOW when low flows are occurring.

These alerts are triggered by flood levels and river management flows, such as minimum flows set for each site. Most of these flows and levels are displayed on the site graphs.

Data Update Frequency

Most monitoring sites measuring river and rainfall information update hourly. Data downloaded from remote sites may vary from this.


Otago Water Plan

The Otago Water Plan includes a suite of water quality rules to ensure good quality water in Otago’s waterways. These rules control contaminants and sediment coming off rural properties into waterways from runoff, leaching, and drains (non-point sources). Landholders are responsible for choosing methods of managing contaminant discharge to waterways that ensure that their property complies with the rules.
