Wyoming Geology & Aquifers
Wyoming's geology ranges from the granitic core of the Wind River and Bighorn ranges to thick Tertiary basin-fill sediments in the large structural basins (Powder River, Wind River, Green River). The Ogallala Formation underlies the southeast, and volcanic terrain characterizes the Yellowstone region with geothermal influences on groundwater.
Understanding your local geology is important because rock type directly affects drilling cost. Hard crystalline rock (granite, gneiss) costs more to penetrate than soft sedimentary formations (sandstone, limestone) or unconsolidated deposits (sand, gravel). Your well driller can estimate costs based on nearby well logs.
Primary Aquifer
High Plains (Ogallala) Aquifer / Madison Limestone Aquifer / Paleocene Fort Union Formation / Mesaverde and Lance Formations
Water table depth: 50-200 feet on the eastern plains; 100-500 feet in intermontane basins; artesian conditions from the Madison Limestone in some areas
Best Drilling Season
May through October; extreme cold, high elevation, and deep snow severely limit winter drilling across most of the state
Population on well water: About 25% of Wyoming households use private wells, reflecting the state's vast ranching landscape and dispersed rural population
Why Well Depth Varies in Wyoming
Wells in Wyoming range from 50 to 700 feet deep. The wide range is driven by regional differences in geology, water table depth, and aquifer type. A well in one part of the state may cost significantly more or less than another area just 50 miles away.
50 ft
Shallowest typical wells
Usually in areas with high water tables, sandy soils, or alluvial aquifers near rivers
220 ft
State average depth
Typical residential well for most Wyoming locations
700 ft
Deepest typical wells
Usually in arid areas, mountain terrain, or where shallow aquifers are depleted
Wyoming Well Drilling Permits & Regulations
Wyoming does not have a state well driller licensing program — one of the few states without one. However, the State Engineer's Office enforces well construction standards, and all wells must be permitted and completed by persons familiar with the regulations.
Permit Authority
- Authority
- Wyoming State Engineer's Office; all wells must have an approved permit before drilling begins
- Permit Cost
- $50-$200
Water Rights
- Doctrine
- Prior Appropriation; domestic and stock wells using less than 25 gallons per minute are generally exempt from formal appropriation but must be registered with the State Engineer
Well Water Quality in Wyoming
Well water quality in Wyoming varies by location and aquifer type. Testing your water at least annually is recommended, and a comprehensive test should be done before using a new well.
Common Water Quality Issues
uranium
Treatment: reverse osmosis or ion exchange system
radium
Treatment: water softener or reverse osmosis
selenium
Treatment: appropriate treatment system
total dissolved solids
Treatment: reverse osmosis system
hardness
Treatment: water softener
sulfate
Treatment: appropriate treatment system
petroleum-related constituents near oil fields
Treatment: appropriate treatment system
Testing Recommendations
- Before first use: Full panel including bacteria, nitrates, pH, and state-specific contaminants ($150–$500)
- Annually: Bacteria (coliform) and nitrate testing at minimum ($50–$100)
- After flooding or repairs: Bacteria test to confirm well integrity ($25–$50)
