20260325 13395300 1.0 TRUE Wells Point features show source locations for Group A and B public water systems. Source location data was obtained by Lewis County Environmental Health and GIS personnel. Most of the point coordinates were collected using sub-meter capable Trimble GPS at the well site; however, topography, vegetation, and structures impact the accuracy of some points. A small number of points were located or had their GPS derived location adjusted using the best available aerial photograph.
