Recommended Method
Based on multiple well logs within the Shell Lake region, the representative geological profile consists predominantly of stratified glacial drift materials. From the surface, wells most often penetrate a thick sequence of sand, sand/gravel, and minor clay layers, occasionally interbedded with silty or stony zones. The most productive water-bearing zones are within coarse sand and gravel lenses, often between approximately 50 to 160 feet below ground surface. Wells are usually cased through the sediment column to isolate these aquifers, which provide typical residential yields (5–15+ GPM), and sometimes higher for large-diameter or deeper installations. Static water levels fluctuate from approximately 12 to 103 feet below ground depending on local hydrogeology and recent precipitation, but are most commonly in the 20–65 foot range.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 20 ft | Sand or sandy gravel (glacial outwash/alluvium) | Loose to medium, red-brown or tan, occasional minor clay or silt, locally stony. | Color: Red to tan/brown Hardness: Loose to medium |
20 – 65 ft | Clay, silt, mixed sand and gravel | Interbedded sandy clay, silty materials, may include some gravel, brown/tan/gray; some caving. | Color: Brown/gray/tan Hardness: Soft to medium |
65 – 150 ft | Sand and gravel (primary aquifer) | Coarse sand and gravel, high-yield water-bearing zone, may include some cobbles; brown to gray. | Color: Brown to gray Hardness: Medium to coarse |
150 – 160 ft | Coarse sand/fine gravel or transition to basal till | Basal sand/gravel layer, locally with clay lenses; transition towards lower permeability layers. | Color: Brown/gray Hardness: Medium |
