White Lake, MI48383
A typical White Lake area well passes through a layer of clay (often brown or sandy with gravel), underlain by significant sand or sand-and-gravel aquifers, and often alternates between finer clays and coarser aquifer material to the base of the investigated depths.

Typical Well Depth
Static Water Level
Recommended Method
Based on a representative sample of well logs from the White Lake region, the generalized subsurface profile starts with a surface layer of topsoil or brown/gray clay (sometimes sandy or gravelly). This is frequently underlain by alternating sequences of clay (blue, gray, or brown) and sand/sand & gravel aquifers of variable thicknesses. The sand and gravel zones are typically medium to coarse, and are the most consistent aquifers. Most residential supply wells are finished in these aquifers between 40-130 feet, with static water levels commonly ranging from 4-33 feet below grade. Residential wells yielding 10-20 GPM are commonly 60-130 ft deep, while higher capacity wells may reach 135-170 ft.
Depth (Feet) | Formation Type | Description | Characteristics |
---|---|---|---|
0 – 3 ft | Topsoil | Topsoil or peat, sometimes absent and replaced by clay directly at surface | Color: Brown/black Hardness: Soft |
3 – 18 ft | Clay | Brown or gray, sometimes sandy or hard, sometimes with stones or gravel | Color: Brown/gray Hardness: Medium to hard |
18 – 35 ft | Clay/Silt/Minor Sand | Gray or blue clay, with some sandy streaks or minor gravel or silt; locally dense/hard | Color: Gray/blue Hardness: Hard |
35 – 55 ft | Sand & Gravel (Aquifer) | Brown or gray, medium to coarse, sometimes with minor clay or silt, main aquifer zone in most logs | Color: Brown/gray/yellow Hardness: Loose to medium |
55 – 70 ft | Clay/Silt (Locally Blue) | Blue or gray clay, may include sandy, silty, or gravelly sublayers; can be hard or plastic | Color: Blue/gray Hardness: Hard |
70 – 110 ft | Sand & Gravel (Aquifer) | Medium to coarse sand and gravel, some zones are fine to coarse sands, often main screened aquifer | Color: Yellow/brown/gray Hardness: Loose |
110 – 125 ft | Clay/Silt (Interbedded) | Generally gray clay, may be gravely or sandy, not always present in shallower wells | Color: Gray Hardness: Moderate |
125 – 145 ft | Sand & Gravel | Gray, brown, or yellow medium to coarse sand and gravel, locally including fine sand layers; thickens in deeper wells | Color: Gray/brown/yellow Hardness: Loose |
145 – 170 ft | Clay with minor sand/gravel | Mainly gray clay with some silty or fine sand or occasional gravel beds; base of logs in deepest sampled wells | Color: Gray Hardness: Moderate |
