Gauge Deventer is on the IJssel at kilometre 945.03, on the km 931–981 stretch.
The OLR is 142 cm and the fairway depth aimed for below it (TuOLR) is 250 cm; after a safety margin of 30 cm, the targeted official rule of thumb comes to Deventer +78.
In practice Deventer +90 is used here, +12 cm against the official rule.
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 5-day forecast from Rijkswaterstaat RWsOS (red). Upstream lies Zutphen, downstream Zwolle, IJssel (Katerveer).
