Downstream flow view — Mekong river width below the cascade

Monthly river width from Sentinel-1 radar at seven reaches located at MRC gauge station coordinates (station codes shown). Width = radar water area in the mapped river channel ÷ reach length. Honest result: on 2023–26 data held out from fitting, upstream dam storage change did not predict downstream width better than the normal for the month at any site (skill ≤ 0). Treat this page as a description of what the river is doing, not a forecast.
