This well is equipped with a pump which may turn on during data collection. Be advised that some water level measurements for this well may be influenced by pumping.

2

This well also collects hourly temperature readings in Celsius (°C). The temperature data are available in the downloads (csv, txt, json).

3

Water level data are maintained by the United States Geological Survey (USGS). The data displayed here are provisional values. Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data. Information concerning the accuracy and appropriate uses of these data or approved versions of the data may be obtained from the USGS.

4

This well also collects hourly temperature readings in Celsius (°C) and conductivity in microsiemens/centimeter (uS/cm). These data are available in the downloads (csv, txt, json).

5

Water level data are maintained by the Edwards Aquifer Authority (EAA). Original data reported in feet above mean sea level, and transcribed by TWDB to feet below land surface using the estimated land surface elevation provided by the EAA.

6

Due to recent repairs to J27, representative water level data from J27 may not always be available due to the periodic influence of nearby pumping wells. If a representative water level reading cannot be obtained from J27 for an entire 24-hour daily reporting period, the representative daily high water level will be obtained from a nearby monitoring well having a very high water level correlation with J27. For more information about this procedure, please contact the EAA.
