National Integrated Drought Information System Water Utilities and Drought Monitoring Map

This National Integrated Drought Information System (NIDIS) Water Utilities mapping application provides a comprehensive visual interface for monitoring drought and water-related conditions across the United States. The interactive map displays real-time streamflow data using a color-coded system ranging from red (low/much below normal) to blue (much above normal), with green indicating normal conditions, overlaid on a geographic map of North America. The application integrates multiple data layers including United States Geological Survey (USGS) streamflow monitoring, National Operational Hydrologic Remote Sensing Center (NOHRSC) snow analysis, Climate Prediction Center (CPC) drought forecasts, precipitation indices, temperature conditions, and various drought indicators like the Palmer Drought Severity Index (PDSI) and Evaporative Demand Drought Index (EDDI). Users can customize their view by selecting from dozens of available layers through the left panel, including administrative boundaries, demographic data, soil moisture percentiles, Vegetation Drought Response Index (VegDRI), Moderate Resolution Imaging Spectroradiometer (MODIS) Evaporative Stress Index (ESI), and Visible Infrared Imaging Radiometer Suite (VIIRS) Vegetation Health Index (VHI), making it a powerful tool for water utility managers, drought researchers, and emergency planners to assess current and forecasted water resource conditions across different temporal and spatial scales.
