There's no single answer, and that's exactly why local knowledge matters so much out here. Across the Hill Country, well depths range from a couple hundred feet to well over a thousand. What you'll hit on your property comes down to which aquifer sits underneath it.
The Trinity Aquifer (much of the central Hill Country)
Across Boerne, Bandera, the north end of Comal County, and into Blanco County, most wells draw from the Middle and Lower Trinity Aquifer. These wells commonly run from a few hundred feet to over 1,000 feet, and the productive zones shift from tract to tract.

The Edwards-Trinity (Plateau) Aquifer (the western hills)
Out toward Kerrville, Real, and Kimble counties, the Edwards-Trinity (Plateau) Aquifer comes into play, with depths that vary widely across the rugged plateau country.
The Llano Uplift aquifers (the northern counties)
Up around Llano, Mason, and San Saba, you're in the Llano Uplift, where the Hickory and Ellenburger-San Saba aquifers can run very deep. The Hickory's artesian zone, in particular, can reach well beyond a thousand feet.
The Edwards Aquifer (the southern edge)
Down toward Uvalde and the south side of Comal and Medina counties, the highly productive Edwards Aquifer of the Balcones Fault Zone can produce strong wells, though depth still varies by location.
Why it matters for your project
Depth is the single biggest factor in what a well costs, and drilling to the wrong depth, or in the wrong spot, is how you end up with a dry hole or a well that can't keep up. Forty years of drilling this exact ground is what lets us target the right depth the first time. See our drilling page, or find your town on our service areas map.
