Texas Well Water Map

See what the data suggests about any Texas property before you buy, build, or drill.

A property in Fredericksburg. A decision in minutes.

You're walking 40 acres outside Fredericksburg with a client. Before the offer goes in, you type the address into Texas Well Water Map.

The site is near Luckenbach, and the map shows a 5-mile area near the property has a 78% drilling success rate — meaning 78% of wells drilled in that area pump more than 5 gallons per minute for more than 8 hours. It also means 22% of drilling projects in that area don't succeed.

Scale it down to half a mile. The map shows the depths of successful wells nearby, which helps you budget for the cost of a new well before the offer goes in.

Five miles is a region. Half a mile is a property. Either way, you walk into the conversation with the data the area has on record — not a guess.
