[Tagging] Waterway directionality in drainage canals

It's the standard to draw a waterway in the direction of flow. I've
questioned this several times, but it's an ingrained default.
My question is more specific: what happens to a drainage canal that
reverses direction? I offer the Everglades and surrounding agricultural
land as an example. There are huge "water conservation areas" that store
water. When it rains, gates are closed and opened to direct water into
these. During a drought, gates send water back out into the canals for
local use. When there's a big storm, water will instead go directly out
So there are a lot of major canals that have no fixed direction. How
should these be mapped? Is there any existing scheme that can show how
water flows under different conditions?
