Streamflow vs. normal: NOAA / NWS Office of Water Prediction, National Water Model analysis and assimilation (experimental NWC Visualization Service "ana_anomaly", 7-day layer). Each stream reach is coloured by its 7-day average flow as a percentile of modeled flows for the same calendar day; reaches between the 26th and 75th percentile (normal) are not shaded. Model estimates, updated daily; not USGS gauge measurements. Public domain. water.noaa.gov
Streamgages: U.S. Geological Survey, Water Data for the Nation — live streamflow (parameter 00060) and gage height (00065) at continuously monitored stations, plus 10 years of daily mean flow, via the USGS Water Data OGC APIs. Status compares the latest flow with daily means for the same time of year (±7 days). Provisional data. waterdata.usgs.gov
Groundwater: U.S. Geological Survey, Water Data for the Nation — daily depth to water at continuously monitored wells (parameter 72019), via the USGS Water Data OGC APIs. Status compares the latest reading with the same time of year (±15 days) in the well's last 10 years. waterdata.usgs.gov
