Well Drillers Near Black Creek, Wisconsin

A geological estimate for the Black Creek area.

Detailed Summary

A representative geological profile for the Black Creek region begins with a surficial clay (sometimes sand or silt) or hardpan layer 25–50+ feet thick, transitions into limestone or dolomite bedrock that often extends 60–200+ feet deeper, and is capped below by a sandstone aquifer. Some logs show intermediate thin hardpan, silt, or occasional gravel, but these are not persistent region-wide. The most reliable sequence is: clay/till, limestone/dolomite, and sandstone. Water is most commonly sourced from open sandstone, but sometimes also partly from fractured limestone. The static water level is usually 40–100 ft below grade. A standard residential well with reliable yields (5–15+ gpm) typically finishes in the upper part of the sandstone and is completed at 120–160 ft, while high-capacity municipal or agricultural wells may go to 180–250+ ft, especially where the bedrock units are thicker or targeted for greater drawdown.
