Water level and depth
Passage Tool compares the live water level at Cologne (Köln) with the gauge's equivalent low water level (GlW). In the section Koblenz - Krefeld the fairway is maintained at a depth of 2.5 m at GlW, so a reading above GlW means more water under the keel than that guaranteed minimum.
Bridge clearance
8 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 Cologne (Köln) reading to estimate today's clearance for your air draft.
