Use the interactive map below to explore water supply data (streamflow, river forecasts, snow water equivalent) alongside drought and climate conditions. Or, view a full-screen version of this map.

Zoom in on the world map here to see how great the demand for water is and how large the gap is between demand and renewable supply in a water province (an area within a country that belongs to a single watershed), or increasingly smaller sub-basins.

2025年2月7日 · Community water system service area boundaries describe the geographic area that receives drinking water from a given community water system. Knowing which water system serves you is important in understanding the source of your drinking water as well as how to obtain answers about water quality and service.

The World Water Map (WWM) is designed to draw public attention to a growing problem: In many parts of the world, demand for fresh water now exceeds the supply from rivers and shallow aquifers that are regularly renewed by rain. To fill those “water gaps,” people are pumping from deep aquifers that aren’t renewable and may eventually run out.
