What is LithIQ? ▾

LithIQ is a predictive groundwater intelligence platform built on 700,000+ Texas well reports from the TWDB Submitted Drillers Report database. It uses spatial modeling to predict subsurface conditions at any location in Texas before drilling begins.

How it works ▾

1Select a county and click anywhere on the map to set your target location, or type coordinates in the sidebar.

2LithIQ finds the nearest historical wells and applies distance-weighted spatial modeling to predict subsurface conditions.

3The predicted lithology column, water depth, and yield are returned based on real driller observations from nearby wells.

5Parcels — toggle the Parcels button to overlay property boundaries on the map. Zoom in to zoom level 13 or closer to see individual parcel lines.

Using the controls ▾

CountyLoads all wells in that county onto the map. Select the county closest to your target site.

CoordinatesClick anywhere on the map to set your target location. The red dot marks your site. You can also type coordinates directly.

Neighbor wellsHow many nearby wells to use for the prediction. More neighbors = smoother prediction, but may include wells farther away.

LithIQ predictions are based on statistical modeling of historical well data and should be used as a planning guide only. Actual subsurface conditions may vary. Always consult a licensed Texas water well driller before making drilling decisions. LithIQ is not a substitute for professional geological assessment.
