Gauge Schoonhoven is on the Lek at kilometre 971.585, on the km 971.6–988.0 stretch.
The OLW is -35 cm and the fairway depth aimed for below it (TuOLW) is 350 cm; after a safety margin of 30 cm, the targeted official rule of thumb comes to Schoonhoven +355.
In practice Schoonhoven +355 is used here.
Note that Rijkswaterstaat publishes an MGD (Minst Gepeilde Diepte, least sounded depth). It always takes precedence, and unlike in Germany, no legal rights can be derived from the official rule of thumb.
This gauge has one forecast source: the 7-day forecast from Rijkswaterstaat RWsOS (red). Upstream lies Hagestein beneden, downstream Krimpen aan de Lek.
