Well Drillers Near Lake City, Michigan

A geological estimate for the Lake City area.

Detailed Summary

Based on a representative sample of Lake City area well logs, the regional subsurface geology is dominated by a heterogeneous sequence of glacial drift. The uppermost 1-4 ft is generally topsoil or fine sand, underlain by variable layers of sand (often brown or light brown), sand with gravel or gravelly interbeds, and occasional clay lenses (usually tan, red, or gray clay, rarely exceeding 10-30 ft in total thickness). The thickest, most productive aquifers are found in sand or sand/gravel intervals, typically starting 10-40 ft below grade and extending variably to 90-160 ft. Clay is present but not regionally continuous; it is often observed as discontinuous stringers or lenses. Typical static water levels range from 10-80 ft below grade, with 5-15 GPM commonly produced at 50-120 ft total well depth. Deeper wells (>150 ft) may be constructed for higher capacity or redundancy, particularly in coarser zones or where static water is deeper.
