What this tracks
This dataset maps the depth and extent of the Ozark aquifer beneath Kansas, showing where this groundwater resource exists and how far below the surface it starts.
Why it matters to you
If you’re drilling a well in Kansas, this data tells you how deep you’ll likely need to dig to reach usable water. Farmers planning irrigation systems can check whether the Ozark aquifer reaches their land before investing in equipment. Cities evaluating future water supplies use this to identify areas where the aquifer is shallow enough for cost-effective wells.
How to read this data
FEET — Depth to the top of the aquifer in feet (sample value: -9999 indicates missing data). Negative numbers mean below sea level.
CODE — Classification of aquifer characteristics (sample value: 222 corresponds to specific rock formations).
OZ_BASE_ — Identifier for mapped aquifer base contours (sample value: 1 shows this is part of the primary dataset).
