This database includes three layers: 1. An inventory of all reported springs in the Driftless Area pre-2025, verified and unverified, compiled from existing data sources. 2. Winter 2025 synoptic spring survey data collected in January-March. 3. Summer 2025 synoptic spring survey data collected in July-September. Synoptic spring survey data for the Driftless Area of Minnesota, Wisconsin, Iowa, and Illinois was collected under baseflow conditions in winter and summer of 2025. Data has been quality-checked, and includes lab analysis results, LiDAR-derived elevations, corrected field nitrate values, and stratigraphic position index. Lab analysis results are reported as null if below detection limit. Only includes springs that are publicly accessible, or springs for which the owner has given permission to share data. Permission may be required to visit some springs. Full metadata and methods described in accompanying publication: Fandel et al. (in prep). A synoptic survey of springs in the Driftless Area.
