# The four regions — ks-water-table

> West, centre and east of the Kansas survey grid, and what the water-table layer covers in each.

## The four regions

Our own grouping of range numbers, not a Survey classification — it exists because the aquifer stops long before the state does.

| Region | Sections | Share | Median change |
|---|---|---|---|
| [Far western Kansas](/region/far-western-kansas.md) | 20,734 | 62.5% | 39.6 ft |
| [Central and western Kansas](/region/central-and-western-kansas.md) | 9,033 | 27.2% | 3.3 ft |
| [Central Kansas](/region/central-kansas.md) | 3,354 | 10.1% | 3.3 ft |
| [Eastern Kansas](/region/eastern-kansas.md) | 69 | 0.2% | 18.0 ft |

This surface covers the High Plains aquifer — western and central Kansas. Eastern Kansas is almost entirely absent (69 sections out of 33,190), and that is not a gap in the data: the aquifer does not extend there. A section with no figure here is not a section with no water.
