Groundwater levels are measured at each site every fifteen minutes and are logged in a datalogger. All levels shown are reported in relation to metres above mean seal level (amsl).
Council currently operates 50 automated groundwater level monitoring sites in the Tasman District. Data these sites are available in real time via the telemetry network. Most of these sites are currently where real time data is required for water management purposes.
Two groundwater level graphs are shown for each groundwater site, one each for the previous 7 and 30 days. Date is shown on the bottom axis, and level (in millimetres) is shown on the vertical axis. The level axis is automatically scaled to the data, so it will vary from one graph to the next. This is important if you are comparing graphs from different sites.
