Detailed Summary
The representative geologic profile for Oconomowoc and the surrounding area, based on sampled well logs, generally consists of about 0-10 feet of clayey or stony material overlying a substantial sand and gravel aquifer (often with intermittent silt or clay layers) extending from around 10 feet to ~110-130 feet. In deeper and southern/western locations, a clay or clay-with-gravel layer may occur from about 40 feet to 125 feet. Below these unconsolidated sediments, limestone (or dolomite) bedrock is consistently encountered, serving as an alternate aquifer, especially for higher capacity or deeper wells. The static water level most commonly ranges from 13 to 35 feet below ground. Residential wells typically end within the deep sand/gravel or just at the top of bedrock, usually between 50 and 125 ft deep to reliably yield 5-15+ gallons per minute.
Expected Geological Layers
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 10 ft | Clay/Stoney Clay/Boulders | Caving to non-caving, brown/grey mottled, variable stoniness and occasional boulders. | Color: Brown-grey Hardness: Soft to firm |
| 10 – 45 ft | Sand & Gravel with minor clay | Clean sand and gravel, mostly water-bearing, may include sublayers of silt or grading from coarse to fine, occasional traces of clay. | Color: Yellow/grey/tan Hardness: Loose to medium |
| 45 – 80 ft | Interbedded sand, gravel, and clay | Some intervals of more clayey gravel, otherwise generally sandy/gravelly, water-bearing. | Color: Grey/tan Hardness: Loose to stiff (clay) |
| 80 – 125 ft | Clay with sand/gravel and possible till | Becomes more clay-dominated with depth in some areas, may have minor boulders, gravel stringers, or silt—transitional to deeper aquifer or bedrock. | Color: Grey/tan/brown Hardness: Firm to hard (clay); loose (sand stringers) |
| 125 – 210 ft | Limestone/Dolomite Bedrock | Massive, hard bedrock, fractured zones may be water-bearing. Aquifer for deeper or high capacity wells. | Color: Buff/light grey Hardness: Hard |
