Minocqua, WI54548-9712
The typical Minocqua-area well penetrates glacial sand, sand/gravel, and minor silty or bouldery zones, rarely reaching shallow bedrock. Most residential wells target an upper unconfined aquifer within these unconsolidated sediments, yielding 5-15+ GPM at depths around 50-60 ft.

Recommended Method
Based on a synthesis of well logs, the Minocqua region is dominated by unconsolidated Quaternary glacial sands and sand-gravel mixtures, sometimes with minor silt, boulders, or thin gravel layers. Bedrock (granite or crystalline) is infrequently encountered and only at greater depths or isolated locations. The typical geologic sequence is sand (0-~20 ft), then gradationally more gravelly and silty sand layers (to 50-60 ft), occasionally with a distinct gravel or sand/gravel aquifer at 50-60 ft. Water is generally drawn from the lower sand/gravel interval, with static water depths between 20-40 ft. Drilled wells are the overwhelming majority, with rotary/mud the preferred method. Casing typically extends to near the top of the main gravely aquifer (50-58 ft), and screens are set in this interval when used. Grout is generally bentonite or cement to at least 20-27 ft.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 20 ft | Sand | Fine to medium sand, loose, occasionally some silt or minor gravel, light colored | Color: Light brown/tan Hardness: Loose to medium |
20 – 50 ft | Sand & Gravel | Fine to coarse sand with increasing gravel with depth; some sections may include silt or boulders. Main water-bearing unit. | Color: Light brown to brown Hardness: Medium |
50 – 60 ft | Sand & Gravel (aquifer) | Coarse sand and gravel, primary water-bearing zone, may include minor cobbles or be open graded. | Color: Brown Hardness: Firm |
60 – 70 ft | Minor clay/silt or possible granite (rare) | Infrequent; may encounter silty gravel or, in rare cases, shallow bedrock (granite or crystalline) at base of profile. | Color: Gray/tan or pink (if granite) Hardness: Very hard if bedrock, otherwise soft |
