Well Drillers Near Black River Falls, Wisconsin

A typical residential well in the Black River Falls area is drilled to approximately 110 feet to ensure a reliable water supply of 5-15+ gallons per minute.

The static water level, or water table, is typically found around 48 feet below the surface in this region.

Based on synthesis of well logs from the Black River Falls area, the most common subsurface sequence is a surficial sand or gravel layer, followed by a substantial thickness of sandstone, with occasional deeper transitions into shale or crystalline bedrock (granite). Sand layers generally extend to 20-40 feet, followed by dominant sandstone formations from roughly 40 feet to at least 105-225 feet. In some locations, deeper sections may encounter shale (around 225-242 ft) or granite (beyond ~250 ft). Casing is typically set to the base of the upper sand or through the unconsolidated overburden into competent sandstone. Typical residential wells (5-15+ GPM) are completed at 80-115 feet, while high-capacity wells (fire protection, etc.) may penetrate to or beyond 250 feet.
