Detailed Summary
Representative well logs from Lake Norden, SD, indicate the following typical sequence: (1) a thin topsoil or fill, followed by (2) yellow/brown silty clay (often mottled or with traces of sand/gravel), (3) blue/gray clay, (4) interbedded sand and gravel layers (main water-producing formation, typically around 30–100+ feet), and (5) deeper clay or till. Static water levels, and productive aquifer zones, are most consistently reported within the sand/gravel intervals at 30–100 feet. Residential wells for 5–15 GPM typically finish at 40–80 feet, though higher capacity may target the base of the thickest sand/gravel layer. Drilling is generally rotary with mud, and cement grout is standard from surface to casing bottom.
Expected Geological Layers
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 2 ft | Topsoil/Fill | Black/brown silty overburden, may include artificial fill in locations. | Color: Black/Brown Hardness: Soft |
