Lao River & Reservoir Coordination System
OneMekong · Hydropower

Managing the Mekong as one connected water network.

A real time basin coordination system integrating reservoir operations, river flows, releases, rainfall, and flash flood risk to support safer, smarter, and more coordinated basin wide water management.

The cascade at a glance

Thirty-one Lao dams — color-coded by active storage status. Tiles show how full each reservoir is right now, relative to its full supply and minimum operating levels. Click any tile to open it in Flow Coordination.

Why this exists

The Mekong cascade is operated by many hands. Reservoirs, releases, and downstream conditions change every hour — but the picture is usually scattered across spreadsheets, emails, and SCADA screens that don't talk to each other.

This platform brings the cascade into one view: a map you can click, charts that update themselves, scenarios you can run, and a place for operators to log what they're doing. It's built for coordination, not control.

Designed with

  • MRC data principles — open, time-stamped, provenance-tagged
  • Operator-first UX — touch-friendly, keyboard-navigable, bilingual ready
  • Honest provenance — every datapoint shows source: manual, CSV, telemetry, or synthetic
  • OneMekong stack — Vercel + GitHub + open mapping tiles, no vendor lock
