The Viroin had been open for 7 days. A dry spell has brought it back down to its 1.6 m³/s lower limit, below which navigation is no longer allowed.

On a river of this profile (Class I-II), 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.
