Water well depth in Utah varies by county, by aquifer, and even from one neighborhood to the next. Here's what the Utah Division of Water Rights driller logs show for typical domestic wells in each county we serve.
Northern Utah
Cache County (Logan area)
Typical domestic wells: 150–350 ft. Cache Valley's Bear River–fed alluvial aquifer is one of Utah's most productive. Logan-area benches reach water around 200–280 ft. The valley floor often goes shallower; the Wellsville bench and east bench typically go deeper.
Box Elder County (Brigham, Tremonton)
Typical domestic wells: 60–200 ft. The Bear River corridor near Tremonton and Garland has remarkably shallow productive aquifers — many domestic wells complete at 60–80 ft. Western Box Elder gets saltier and deeper.
Weber County (Ogden)
Typical domestic wells: 150–400 ft. Weber County has a confined principal aquifer that most modern domestic wells target. Older artesian wells in lower Ogden tap perched zones at 30–50 ft, but those don't represent modern construction.
Morgan County
Typical domestic wells: 100–400 ft. Morgan Valley itself is shallower; the surrounding canyons and benches require deeper wells through harder formations.
Wasatch Back
Summit County (Park City, Coalville)
Typical domestic wells: 200–600+ ft. Summit County depths vary dramatically. Park City and the Snyderville Basin pull from deep bedrock aquifers, often 350+ ft. Kamas Valley alluvial wells are shallower. Coalville-area wells are moderate.
Wasatch County (Heber City)
Typical domestic wells: 150–500 ft. Heber Valley floor wells are usually shallower (180–300 ft); bench and mountain-edge wells run deeper. Midway tends to be shallower than the eastern Heber benches.
Wasatch Front
Utah County (Provo)
Typical domestic wells: 100–400 ft. Wide variation across the basin. North-county benches (Highland, Alpine) tend deeper. Southern county and Goshen Valley have well-developed alluvial aquifers at moderate depth.
How to get a depth estimate for your specific address
The above are county-wide ranges. Your specific lot may differ from the county median by hundreds of feet. The Utah Water Well Cost Calculator reads your nearest neighbors' actual driller logs and gives a depth estimate based on what they actually drilled. That's much more useful than a county average — especially in counties like Summit and Wasatch where depths vary block by block.
