Eagle River, WI 54521
Eagle River area wells commonly encounter surficial sand or sandy soil, transitioning to sand and gravel (sometimes silty or clay-bound), with local lenses of clay, silt, or boulders. Productive aquifers are dominantly found in sand and gravel units from about 20 to 120 feet. Wells for residential use typically require drilling to 40-110 feet for adequate yield.

Across Eagle River, Vilas/Oneida County, well logs reveal a typical unconsolidated glacial sequence: (1) upper fine to medium brown sand or sandy loam, (2) locally a band of silty sand or silty clay, (3) thick section of mixed sand and gravel—sometimes with interbedded boulders or clay lenses, (4) deeper intervals often transition to cleaner sand and gravel or semi-coarse sand. Few wells reach bedrock at these sampled depths; most production zones are unconsolidated. Static water levels are typically between 10-36 feet below grade. Residential wells to ~40-110 feet routinely yield 5-20 GPM. Deeper (100-120 feet) completions are selected for higher capacity or site-specific needs.
