Realtime Flood Data Groundwater Levels

This record is for Approval for Access product AfA421. Realtime Flood Data Groundwater Levels, this dataset covers monitoring data that is only updated on our systems on a daily update cycle. This is usually increased during times of flooding etc. Readings are transferred via telemetry to internal and external systems in or close to real time.
