Researchers at Virginia Tech created a national database of water withdrawals. They collected records from state agencies and standardized data from many states. The database includes withdrawals from rivers, lakes and underground aquifers and offers monthly and annual data when available.
The dataset focuses on self‑supplied withdrawals, meaning water taken directly from a source, not deliveries to homes or businesses. Early results show that about half of recorded entries are for agricultural irrigation, while the power sector withdraws the largest total volume each year. The database is publicly available to help communities and policymakers plan and manage water use.
