Rhine at Lobith, Netherlands: Below normal, 12th percentile of its own record
Open methodology
A watch point's latest GloFAS discharge is located on its stored quantile grid for the same seasonal pool. Each river then uses its outlet point when scored, or the mean of its scored points when the outlet is unavailable.
Formulapoint p = linear position of Q between stored percentile-grid values; river p = scored outlet p, else mean(scored point p)

Published resultRhine at Lobith, Netherlands: Below normal, 12th percentile of its own record
Data & provenanceGloFAS v4 daily river discharge via Open-Meteo; the percentile grid is built here from complete stored years. Open this model coordinate
LimitAt least five complete years and enough observations in the seasonal pools are required. Unscored, stale and suspect points stay out of every denominator rather than being treated as normal.
Model data: 06 Sept
41 of 101 scored European rivers are below their normal range.
29 have exceptionally low flow and 6 have exceptionally high flow for this time of year.
Open methodology
Each model point is placed in its own seasonal record. A river uses its scored outlet point when available; otherwise it uses the mean percentile of its scored points. The headline then counts rivers, so a river with several watch points still has one vote.
Formulariver p = outlet p, else mean(scored point p); exceptional signal if rivers below P10 ÷ scored ≥ 20%; else below-normal if rivers below P25 ÷ scored ≥ 34%; else within range

Basin flow data is currently unavailable.
The homepage now starts with the river map. River details sit beside it, with the status summary and basin comparison below.
A redesigned footer and native arrow icons make navigation clearer on desktop, tablet and mobile.
Live reservoir readings and history now load independently, with clearer observation times and usable storage figures. The river reservoir table no longer duplicates dams, and available reservoir data stays visible while river gauges load.
Dated drought context explains Slapy's role in supporting downstream flows. Instantaneous zero outflow is distinguished from daily releases.
