13,609 surveyed sections, drawn 3 by 3 miles to a square. The shading is scaled against every county in Arizona, so a colour means the same thing on any of these pages. The outline is the county boundary from the Census Bureau: ground inside the line and outside the shading is ground nobody has drilled, filed on or addressed. Aerial imagery is the USGS National Map.
Stands out
The water here stands a long way below the surface
The water table sits 372 feet down in the typical square mile, against 150 ft across the state. That is not the depth of the hole, it is where the water stands in it, and it sets the pump, the lift and the power bill for as long as the well runs.

Stands out
Wells here come in weak
The typical well makes 12 gallons a minute, against 20 gpm across the state. A household needs roughly 5 to 10, so this is liveable and it will not support irrigation, livestock at scale, or a second home on the same well.

Worth knowing
The water table here is falling faster than it used to
Twenty years of monitoring show -1.5 feet of change and the last ten show -2.2. Half the record has produced more than half the drop, so the decline is steepening rather than levelling off. A well drilled to a depth that worked ten years ago has less margin than the twenty-year figure suggests.

Context
Wells here have to go a long way down
The typical well is 398 feet deep, across 15,717 wells on record. Drilling is priced by the foot and the casing with it, so depth is the first line of any estimate for putting water on raw land, and it is the number a seller is least likely to volunteer.

Context
Nearly every monitored well here is falling
72% of the 99 wells ADWR has monitored for twenty years are declining rather than recovering. This counts wells, not feet: a county can be losing only a foot a year and still have almost every well in it pointing the same way, which is what says the drawdown is regional rather than one heavy pumper.

Worth knowing
Parcels here are large
The typical parcel is 120 acres. Size is the reason the water question is worth asking: a large parcel with no water is a large parcel you cannot do anything with.

This is the county. Your question is probably a property.
None of the above is about a particular parcel. Water is not parcel-shaped: the ditch serving the ground runs through other people's land and the senior right that curtails it sits somewhere else, which is why the state files by survey section rather than by property. Check an address and you get the square mile it sits in, with the wells, the rights and what was actually diverted.
