Detailed Summary

The representative geological profile for Sturgis, SD, consists of a thin surfical sequence of clays, silty and clayey gravels, and sand, usually extending from land surface to approximately 25-30 feet. This is typically underlain by substantial sequences of shale, interbedded limestone and gypsum, with thick sandstone units at depth. The most reliable and productive aquifers are the Minnekahta and Madison limestones, frequently encountered between 240 to 960 feet. Deeper wells may pass into the Deadwood Formation (sandstone and shale), particularly for high-capacity or municipal supply. Shallower residential wells typically target the upper limestone or sandstone units and are commonly completed between 150 and 350 feet below surface. Static water levels in residential wells are typically 40-150 feet, while deep municipal wells can have static levels near 400-500 feet.
