Around here the water levels can vary +/-0.5m (just before the bridge
there's a gauge so you can tell at any particular moment if you'll
fit). Should the height here be the "minimum maximum_height"? The
maximum height when the water is the heighest?

Probably need a width too, since the bridge opening is not as wide as
the water around it... And a depth, also the minimum maximum
measurement.

Have a nice day,
