The Semois had been open for 20 days. A dry spell has brought it back down to its 2.2 m³/s lower limit, below which navigation is no longer allowed.

On a river of this profile (Class I — family-friendly), summer low water is the rule rather than the exception. Reopening depends on several days of rain over the upper catchment — a single shower is not enough.
The other rivers have different thresholds and catchments: one can be navigable while another is not. You can compare their status live, or ask to be told by e-mail as soon as it reopens.
