Datastream | Ground Water Levels
| Measurement of static groundwater depth in a water well, as measured below land surface
| Agency: NMBGMR

ObservedProperty | Depth to Water Below Land Surface
| depth to water below land surface (NOTE: THIS IS NOT ELEVATION of Water, if elevation is reported, depth to water below land surface must be calculated using land elevation and measuring point.)
| Option of Null, Dry, or qualifications on observed property | |
Sensor | Pressure
| Continuous measurement depth to water in Feet below ground surface (converted from pressure reading and QC’ed from depth below land surface in feet)
| |
Sensor | Acoustic
| Continuous measurement depth to water in Feet below ground surface (converted from acoustic device, QC’ed)
| |
Sensor | Manual
| Manual measurement of groundwater depth by steel tape or electronic probe or other
