Detailed Summary

Based on multiple well completion and plugging reports sampled from Hot Springs and adjacent regions, the most common geologic sequence is a thin surficial cover (sand, silt, clay, or topsoil) followed by several distinctive consolidated sedimentary formations, starting with Spearfish, then Minnekahta limestone, Opeche shale, and reaching primary Minnelusa sandstones. The Minnekahta and Minnelusa units serve as main water-bearing zones. Average static water levels are reported between 100–300 ft, and wells for typical household supply (5–15 GPM) are usually drilled to depths of 360–380 ft, with higher yields possible below 380 ft.
