River Flow

Tasman District Council monitors river levels and flows on a number of rivers across the District at automatic recording sites. Click on the map markers or links below to find up to date information on river flow in Tasman District.

Webpage Update

Due to a few technical issues associated with a data upgrade the map below is currently not working. We apologise for any inconvenience caused by this. Please use the menu down the left side of the page to find the site you are interested in. We are hoping to have this fixed by the end of January 2017.


Two river flow graphs are shown for each flow site, one each for the previous 7 and 30 days. Date is shown on the bottom axis, and flow is shown on the vertical axis. The flow axis is automatically scaled to the data, so it will vary from one plot to the next. This is important if you are comparing graphs from different sites.
