Water level and depth
Passage Tool compares the live water level at Mainz with the gauge's equivalent low water level (GlW). In the section Lauterburg - Budenheim/Niederwalluf the fairway is maintained at a depth of 2.1 m at GlW, so a reading above GlW means more water under the keel than that guaranteed minimum.
Bridge clearance
5 bridges in this section use the CCR rule of 9.1 m clearance at the highest navigable water level (HSW). Passage Tool adds the difference between HSW and the current Mainz reading to estimate today's clearance for your air draft.
