Detailed Summary

The representative subsurface profile in the St Croix Falls area consists of a thin topsoil or surficial organic layer (0–2 ft), immediately underlain by interbedded sand, gravel, and occasional lenses of clay (to ~70–80 ft in most wells; deeper, >200 ft in some). Locally, there may be zones of coarse gravel, sandrock, or significant clay beds (esp. 50–75 ft and 75–238 ft in deep wells). Wells rarely penetrate bedrock, but if drilled deeper, hard trap rock or limestone (limerock) is found from ~75 ft or as deep as 300+ ft (only in deepest wells). Most residential wells are completed in the sand & gravel aquifer at ~60–140 ft, with static water levels typically 30–75 ft below ground. Wells yield 6–20+ GPM where thick sand/gravel is present.
