### Section by section

*Township 18S Range 40W — depth to water before the aquifer was developed, against the 2022–2024 surface, in feet below ground. A plus sign means the water is deeper than it was; a minus sign means it is shallower. A dash means one of the two is missing; ≥ marks a change computed from a figure floored at ground level.*
