Description
Aquifer
A code or concatenation of codes identifying the aquifer(s) in which a water well has been completed. See Aquifer Monitored Codes on the Code Definitions page.
Class
Identifies the class (or type) of the well. A well may have multiple classes. See also Well or Monitoring Point Classification Codes on the Code Definitions page.
Data Source

Code identifying the group or agency who collected, or was responsible for, the collection of the record. Applies to Water Level, Salinity, Well Yield and Water Chemistry records.

See Data Source Codes on the Code Definitions page.

Extract Method
A unique code indicating the method by which water was extracted from the well.
See Extraction Method Codes on the Code Definitions page.
Measure Method
Code identifying the method used for measuring the yield of the water well.
See Measurement Method Codes on the Code Definitions page.
Measured During

Code identifying the activity during which the measurement was recorded. Applies to Water Level, Salinity, Well Yield and Water Chemistry records.

See Measured During Codes on the Code Definitions page.

Name
Name of the well, if available.
 
Also shown on the Water Chemistry tab as the name of the chemical (analyte) corresponding to the chemical code.
Network(s)

Code identifying one or more observation networks to which the well is associated, if applicable.​

Obs Date
Observation Date. The date on which the reading was measured. Relevant to:
  • Water Level details: Depth To Water (DTW) or pressure.
  • Well Yield details: Yield measurement.
Obswell No.

Unique code identifying the water well as ​an observation well, i.e. monitored for water levels. An observation well is associated with the relevant Obswell Network.

Not all water wells are observation wells.

Permit No.
Well construction permit number applicable to the drilling/contruction activity.
The Summary details show only the last permit number issued.
Previous/Next
Available when multiple wells are found. Click to navigate to the details of the previous or next well.
Unit Number

​First component of the Unit Number is a unique number for the 100,000 map sheet on which a drillhole is located.

Second component of the Unit Number is a unique number identifying the drillhole on the 1:100,000 map sheet

 

Yield (L/sec), Date
The recorded rate (L/sec) at which water is extracted or flowing from the water well, and the date it was measured.
The Summary details shows only the latest observed rate and date.
