Detailed Summary

Wells in the Gillett region commonly encounter a surficial sand or sand/gravel layer, followed by a sequence of clay or sandy clay. This is typically underlain by a coarser sand or gravel unit, and most wells finish in water-bearing sandstone, which provides reliable yields. The static water level commonly ranges from 5-25 ft below ground. Residential wells yielding 5-15+ GPM are typically drilled to 60-100 ft, while higher capacity wells or those targeting more robust sandstone aquifers may go deeper (up to 180 ft or more).
