Gauge Grein is on the Danube at kilometre 2079.1, on the km 2094.5–2060.42 stretch.

Fairway depth and rule of thumb

At RNW 668 cm, the site uses 250 cm fairway depth and a 30 cm margin: Grein -448. This is a reference calculation, not a current sounding.

This gauge is in an impounded reach. Use soundings and navigation notices for the available depth; a water-level rise here does not give the same increase in fairway depth.

High water: Marke I and Marke II

Marke I (HSW): 860 cm. Navigation may be suspended above Marke II (950 cm).
