Andhra Pradesh Groundwater Assessment

Groundwater Status Map

What this is: Every mandal coloured by one measure at a time: groundwater, rain, water balance, crop vegetation or the official category.
What it says now: The State's 1,746 wells averaged 11.4 m below ground on 9 Sep, 3.2 m deeper than a year ago. 402 mandals read groundwater stress.
What to do with it: Switch the layer to compare measures; select a mandal to open its record.

Basemap © OpenFreeMap · OpenMapTiles · OpenStreetMap. 595 of 670 mandal outlines are rebuilt from the State's official boundary points (AWARE); the rest are public prototypes.

Coverage: 669 of 670 prototype mandal boundaries have a measured or modelled depth; 1 have no usable APWRIMS series yet (shown grey).

What do these levels mean?

Status — groundwater stress

StressDeep or fast-declining water table — act first≥15 m below ground & satellite agrees (dry), or fast-falling trend

WatchModerate decline, rainfall deficit, or deepening6–15 m below ground, monitor signal

NormalShallow / stable — routine monitoring≤6 m below ground, stable or recovering

VerifySensor reading diverges from the model — field-check before actingReading outside the model's own P10–P90 by more than half that band's width

Low ConfidenceSparse sensor history — collect more readings<2 stations, or no reading in the last 90 days

Signal — why it's declining

Pumping-pressure (verify)Falling despite a healthy water balance — hypothesis, confirm in field

Climate-stress (verify)Falling alongside a rainfall deficit — climate-stress hypothesis, confirm in field

Stable / recoveringWater table holding or rising

Grey mandals have no estimate yet (insufficient / unmatched APWRIMS history). Levels are modelled (β) — see Modelled Levels.

Measured & Modelled Values

These are not competing sensor readings. APWRIMS is observed depth history; the β value is this app's calculated mandal groundwater level for the current target period.

Backed by its recordForecasts made in September after near-normal rain beat assuming no change by 12% (2.06 m against 2.35 m average error over 5 years). They expected less water than came, by about 0.7 m. Rain here over the three months to the forecast: +2% against normal.

Only the three-month horizon is released, on rolling-origin validation. Both ranges are model P10–P90 quantile ranges, not guaranteed confidence intervals.
