Lake Ann area typical well is drilled with rotary mud circulation, cased to 50–150 ft, and typically passes through alternating sand/gravel and clay layers, with most residential wells 60–120 ft deep, screened in major sand/gravel aquifer zones.

Open guide →A geological estimate for the Lake Ann area.
Based on synthesis of sampled well logs from the Lake Ann region, the most representative subsurface section includes: a thin topsoil/sand layer, followed by a sand and gravel unit, then interbedded clay and sand/gravel sequences, often with repeated alternations. The primary aquifer is commonly a medium to coarse sand/gravel unit. Clay layers are prevalent between 30–120 ft, with sand or sand/gravel again prevalent below. Average residential static water level is about 35–55 ft; typical residential wells target the main sand/gravel aquifer at 80–110 ft, while higher capacity/irrigation wells extend to 200–270+ ft and target deeper sand/gravel. Most wells use rotary drilling with bentonite slurry grout and PVC casing.
| Depth (Feet) | Formation Type | Description | Characteristics |
|---|---|---|---|
| 0 – 2 ft | Topsoil/Sand | Brown or tan topsoil with fine sand, thin organic surface. | Color: Brown/tan Hardness: Loose |
| 2 – 25 ft | Sand & Gravel | Medium to coarse sand with gravel. Good permeability, minor cobbles possible. | Color: Tan/brown Hardness: Loose-medium |
| 25 – 55 ft | Gravel, Sand, & Clay (Interbedded) | Alternating layers of sand, gravel, and clay; occasional stoney zones. Lower permeability. | Color: Tan/gray Hardness: Medium-firm |
| 55 – 80 ft | Clay with Sand/Gravel Stringers | Gray or tan clay with intermittent sand/gravel lenses, common confining layer. | Color: Gray/tan Hardness: Firm |
| 80 – 120 ft | Sand & Gravel | Main aquifer: medium to coarse sand with gravel, high permeability, target for wells. | Color: Tan/yellow Hardness: Loose |
| 120 – 170 ft | Clay/Sandy Clay | Stiff gray to tan clay, lesser sand stringers, second confining interval in deeper wells. | Color: Gray/tan Hardness: Firm |
| 170 – 250 ft | Sand & Gravel (Deep aquifer zone) | Coarse sand and gravel, high-yield zone for high-capacity/irrigation wells. | Color: Gray/yellow Hardness: Loose |
