Vellore district
100% of the irrigated farmland is watered from wells (Season and Crop Report 2024-25), 5 of 6 taluks already draw more groundwater than recharges, and all 2,19,410 households on the JJM register are recorded with a tap, a 100.0% that reads as a reporting convention rather than a measurement.
Read as of 2026-09-06, from 247 Gram Panchayats in 7 blocks, 242 of them with a brief that cleared the evidence floor.
24,223 ha net irrigated: canals 0%, tanks 0%, tube and bore wells 9.3%, open wells 90.7%, other sources 0%.
District stage of extraction 121.8%, assessed over-exploited. Assessed per revenue taluk, not per block or Panchayat.
2,19,410 connections against 2,19,410 households in 242 Panchayats. Exactly 100.0% is read as reported complete, not measured.

What the district runs on
Irrigation from the district tables of the Season and Crop Report 2024-25, with the Census 2011 village pattern beneath it as the block-level baseline; drinking water from the sources JJM records today. A Panchayat without a measure lowers that measure’s denominator rather than counting as a zero.

- Tanks0.0%(0 ha)
- Tube and bore wells9.3%(2,252 ha)
- Open wells90.7%(21,972 ha)

Season and Crop Report 2024-25, Table III-B, the district total: gross 32,572 ha with 8,348 ha irrigated more than once (intensity 1.34).

Census 2011 village tables, covering 149 of 247 Panchayats with a land record. Kept beneath the current reading because it is the only served source with a block gradient.

JJM, read 2026-09-06. Commonest source types: Deep Tubewell (4,450), Infiltration well (183), Open Well (110), Shallow Tubewell (23).
99.0% of the 4,814 drinking-water sources JJM records here draw on groundwater (4,450 of them deep tubewells), against 24 on surface water.
Groundwater by taluk
IN-GRES assesses revenue taluks, not blocks or Panchayats. These are the units the district is actually assessed in, and the headroom reading is written from them.
IN-GRES 2024-2025 puts total groundwater availability across the 6 taluks at 18,174 ham a year, 7,848 ham of it rainfall recharge, with 665 ham (3.7%) left for future use. Of the 6 taluks, 5 over-exploited and 1 semi-critical. The district as a whole is assessed over-exploited at 121.8% of extraction. Headroom sits mostly in Katpadi (298 ham) and is thinnest in K V Kuppam (1 ham).
| Taluk | Stage of extraction | Category | Rainfall recharge (ham) | Total availability (ham) | Left for future use (ham) | Rainfall (mm) |
|---|---|---|---|---|---|---|
| K V Kuppam | 150.8% | over-exploited | 960 | 2,143 | 1 | 978 |
| Anaikkattu | 148.1% | over-exploited | 1,554 | 4,617 | 36 | 946 |
| Gudiyattam | 120.5% | over-exploited | 1,243 | 3,816 | 171 | 940 |
| Vellore | 112.3% | over-exploited | 1,013 | 2,556 | 52 | 1029 |
| Pernambut | 106.3% | over-exploited | 1,032 | 1,629 | 107 | 951 |
| Katpadi | 83.7% | semi-critical | 2,047 | 3,413 | 298 | 988 |
IN-GRES 2024-2025. The stage of extraction is annual draft as a share of total availability; above 100 percent, more is drawn each year than the taluk is assessed to have. Rainfall recharge is one component of that availability. The year is the hydrological-year label, not an edition date. 247 of 247 Panchayats inherit their containing taluk's category by spatial intersection, as containing-area context rather than a measurement of the place; 0 are deferred rather than guessed.
Blocks compared
The same measures per block. Where a district average hides a gradient, this is where it shows, and the findings are written before the table rather than left for the reader to find.
Canal share runs from 0.0% in Anaicut, Gudiyatham, K.V. Kuppam, Kaniyambadi, Katpadi, Pernambet and Vellore to 0.0% in Anaicut, Gudiyatham, K.V. Kuppam, Kaniyambadi, Katpadi, Pernambet and Vellore; wells fill the difference, 100.0% of irrigated farmland at the bottom of the gradient against 100.0% at the top.
No block reports a tap gap: every block records exactly 100.0% of households with a connection.
7 of 7 blocks report exactly 100.0% of households with a tap, and so does the district as a whole. A figure that exact across 2,19,410 households is a reporting convention, connections entered equal to households, and is read here as reported complete rather than measured.

Canal, well and tank figures are shares of the irrigated farmland beside them, not of households and not of drinking water. They come from Census 2011 (Census 2011 release; village reference year 2009) and cover only the 149 Panchayats with a Census land record, so a block with few such records shows a share of a small area. Tap and testing figures are JJM and current at the read date. The talukcategory is the one most of the block’s Panchayats inherit by projection, since blocks and revenue taluks do not nest. Untested counts Panchayats whose most recent water-quality sample is more than 90 days before 2026-09-06; ninety days is the Atlas’s own threshold for calling a series stale, not a statutory testing interval.
Floods and scarcity
Two readings the directory families cannot carry: what the state's own disaster plan says about flood exposure here, and - where the state publishes one - the week's tanker register. Both are the state's documents, quoted and dated, not the Atlas's assessment.
Vellore is not among the fourteen coastal districts the state disaster plan rates highly vulnerable; the plan does not classify inland flood exposure district by district, so that is the extent of what it states here, not a rating of safety.
“The 14 coastal Districts, viz., Chennai, Kancheepuram, Tiruvallur, Cuddalore, Villupuram, Thanjavur, Tiruvarur, Nagapattinam, Myladuthirai, Pudukottai, Ramanathapuram, Thoothukudi, Tirunelveli and Kanniyakumari are highly vulnerable and affected frequently by the trough and depression formed in the Bay of Bengal and Indian Ocean during South-West and North-East monsoon periods.”
Water bodies
The TNGIS all-water-bodies register, joined to each Panchayat by the register's own LGD code rather than by a name match.
In 215 Panchayats; 32 have none in the register. Registered by AED, DOSS, NRSC, TNRD, WRD. Waterspread is the mapped extent, not storage: it says nothing about whether these hold water through the year or when any one of them was last surveyed. Read 2026-09-06.
Polluted river stretches
What CPCB's October 2025 (updated version) report lists for the district. Priority is CPCB's own BOD band on the 2022 and 2023 maximum, I the worst; station BOD for 2024 is the report's follow-up annexure. Each row says how it was joined to the district: a place CPCB prints, or the river's course.
Not yet on file for this district
Named gaps, kept short: each becomes a section of its own when its source is wired.
- District Environment Plan. Every district files one on the NGT template, with a water balance in it; the plan for Vellore has not been acquired, and this stays a named gap rather than an estimate until it is.

Every one of the 247 LGD-coded Gram Panchayats is listed. A place shows a water profile only where its evidence cleared the floor (identity, population and drinking-water service established); the rest are directory records, kept so they can be found and reviewed.

The district on a map
Every Panchayat with a mapped boundary is plotted from the centre of its own TNGIS polygon, not from a hand-entered coordinate. The marker is the Panchayat, not a settlement.
247 of 247 Panchayats have a mapped boundary. The polygons are not drawn on this page.
How current these figures are
Not everything on this page is from the same year, and the gap is large. What each figure describes is listed separately from when the Atlas last read it, straight from each artifact's own record.

The land, irrigation and seasonal-source figures are the oldest thing here by a wide margin. India’s 2021 census did not take place, so Census 2011 remains the most recent village-level enumeration and there is no newer source of the same granularity to replace it with. Those figures are kept under capabilities named historical, and the current-crop capability is left empty rather than answered with a 2009 number.
