The average ground water level in metres for each district, every month of the year.
What this page shows, in plain words
What it shows
The average ground water level for each of the 38 districts in every month, with a yearly average.
Reading the number
Figures are in metres, as printed. The report does not say on these pages how the level is measured (for example, as depth below ground level), so we show the number and the unit and nothing more.
Gaps
A dash in the report means no figure. It is shown as “not reported”, never as zero.

Notes and checks
- As printed. Every figure is shown as the report prints it. We do not recalculate averages, deviations, shares or totals. Bars and segments are drawn in proportion to the printed figures.
- District names. The pages use the official names from our district list. The report spells three of them differently (Sivagangai, Tiruchirapalli, Villupuram); the downloads use the official names too.
- Not reported. Where the report prints a dash or leaves a cell empty, we show “not reported” (a blank in the downloads), never zero.
- Different source. These readings come from the State Ground and Surface Water Resources Data Centre, not from the Department of Economics and Statistics, which only prints them.
- Gaps. The report prints a dash in 12 cells, all for Chennai: 11 months and the yearly average. Only October 2024 has a figure.
- Yearly average. The printed yearly average is within 0.5 m of the mean of the printed months for all 38 districts. It is shown as printed.
- Measure. The report gives no definition of the measure on these pages. The unit is metres.
- June 2025. It falls after the agricultural year (June 2024 to May 2025) but the report prints it in this table, so it is included.
