The typical Barron County well encounters topsoil underlain by clay and gravel, followed by extensive sand/gravel aquifers and, in deeper wells, yellow/brown sandstone. Most residential wells are completed in the sand/gravel or shallow sandstone at moderate depths.

Recommended Method
A representative Barron County well begins with a thin layer of topsoil or organic matter, followed by a thick, typically noncaving layer composed of brown or yellow clay, gravel, and occasional cobbles. This is underlain by a sequence of caving sand and gravel—usually brown or yellow—which acts as the primary aquifer for most wells. Deep wells may penetrate into noncaving yellow or brown sandstone and sometimes thin shale. The majority of residential wells (yielding 12–20+ GPM) are completed at 70–90 feet, while higher capacity or municipal wells may extend to 150–180 feet to reach bedrock or thick, permeable sandstone. Static water levels are variable but commonly fall in the 25–40 ft range.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 1 ft | Topsoil/Organic | Thin surface layer, black, may be organic-rich or silty. | Color: Black/Tan Hardness: Soft |
1 – 12 ft | Clay, Gravel, occasional Cobbles | Dense brown/yellow/gray clay layers frequently with gravel and occasional cobbles or boulders. Transitional to aquifer below. | Color: Brown/Yellow/Tan Hardness: Firm to hard |
12 – 45 ft | Sand & Gravel | Water-bearing, unconsolidated brown/yellow sand and gravel, main residential aquifer. May be caving. | Color: Brown/Yellow Hardness: Loose to medium |
45 – 80 ft | Sand & Silt, with Clay or Shale interbeds | Alternating zones of sand, occasional gravel, occasional interbedded silt/clay; transitional zone before bedrock/sandstone. | Color: Yellow/Brown/Tan Hardness: Medium |
80 – 155 ft | Sandstone (sometimes with shale) | Noncaving yellow or brown sandstone, may include thin shale beds. Often open hole in deeper wells. | Color: Yellow/Brown Hardness: Hard |
