Water Data Exchange (WaDE) Program
Legacy & Transition Hub
What is WaDE?
For more than fifteen years, the Water Data Exchange (WaDE) helped western states share water rights, water supply, and water use data in standardized formats to support regional analysis. WaDE’s public interface, WestDAAT, enabled cross-state discovery and visualization of water data to inform planning, research, and public understanding.
WaDE was cutting-edge when it launched—built to meet a real need at a time when many states did not yet have robust, public-facing water data tools.
What is happening to WaDE?
WSWC is no longer hosting WaDE/WestDAAT services. These tools will be brought offline and archived.
Western states have made major strides in the last 15+ years. Most state agencies now provide state-operated, public-facing water data portals that include the context, caveats, and state-specific interpretation that are critical for accurate public use.
At the same time, WaDE and related tools have historically relied on time-limited grant funding. With that grant support ending and WSWC members prioritizing core policy and coordination functions. For the most up-to-date authoritative water data resources, see the compiled list of state water data portals below.
Where To Access Water Data Now (authoritative sources)
State Water Data Portals (Official Sources)
These state-run systems are the best source for authoritative water rights administration information, state-specific data definitions, and governing context.
Other Commonly Used Federal Resources
USGS (streamflow and related monitoring)
Bureau of Reclamation (reservoir operations and related resources)
Frequently Asked Questions
Will WaDE/WestDAAT still be available after April 2026?
WaDE/WestDAAT services will remain offline and sunset for the foreseeable future.
Where should I go if I previously relied on WestDAAT for data downloads?
We recommend using your state’s official portal first. WSWC’s State Data Portals page provides direct links.
Why is WSWC doing this?
This transition reflects…
- the strong progress states have made in providing public access to data.
- the reality that long-term operation of a multi-state technical platform requires sustained funding and capacity beyond WSWC’s core mission.
Who is the authoritative source for these data?
State agencies remain the authoritative source for state-administered water rights and related water management data.
