We’re pleased to announce the release of BWI service v2.16.00, bringing meaningful improvements to forecast horizon, data transparency, and platform performance.
V2.16.00 extends BWI’s river flow forecast horizon to 15 days, downloadable and readable via API — a significant milestone for the BWI team and for operational hydrology.
Until now, up to 10-day forecasts were the standard across BWI’s services. With V2.16.00, users can now access half a month of hydrological visibility, the longest forecast horizon ever offered by BWI.
Why does it matter? Because operational decisions require time.
Reservoir operations, maintenance planning, flood preparedness, irrigation scheduling, and stakeholder coordination rarely happen overnight. In many situations, having visibility 15 days ahead can make the difference between reacting to an event and preparing for it.
For basin managers, hydropower operators, irrigation agencies, and water-dependent industries, those five additional days provide valuable lead time to anticipate risks, coordinate actions, and make more informed decisions before a hydrological event reaches a critical threshold.
Early warning alerts can now be configured up to 13 days ahead, meaning the extended horizon doesn’t simply provide longer forecast, it directly strengthens anticipation capabilities through BWI’s alert system.
The 15-day forecast is currently available via the download function and API. Portal visualization of the full 15-day horizon will be introduced in a future release.

V2.16.00 introduces Data Origins, now accessible through the API.
This new feature provides visibility into the data sources behind each virtual station’s forecasts and near real-time estimates, helping answer a common question from technical and operational users alike: where does the data come from?
By improving traceability and transparency, Data Origins supports validation workflows, facilitates reporting requirements, and helps organizations better document the information used in operational and regulatory contexts.
The feature adds an additional layer of interpretability and auditability to BWI’s outputs without requiring any changes to existing API integrations.

Performance has also been significantly improved in this release.
Forecast and Near Real-Time data display — up to 7 days ahead — now loads in an average of 13 seconds, compared to 22 seconds previously. That’s a 40% reduction in loading time.
For users relying on the platform every day, faster access to hydrological information means less waiting, smoother navigation, and a more efficient operational experience.
As forecast horizons grow and monitoring requirements become more demanding, performance remains a critical part of delivering actionable water intelligence.
These improvements benefit organizations that rely on hydrological intelligence for daily operations, including basin authorities, hydropower operators, irrigation agencies, engineering teams, and industrial water users.
This release reflects our ongoing commitment to providing more actionable hydrological intelligence, greater transparency, and a smoother operational experience. We’re proud of the progress and look forward to sharing what’s coming next. 💧
