Transportation is not transmission. Transportation of water over a canal
means loading water into boats and send them over the canal.
Those canals aren't intended to transmit water like the Los Angeles
Aqueduct does.

Many headrace or transportation canals can also serve a water discharge
where local drains end.
Drainage can't be the first usage because if drainage water stops,
transportation, navigation and irrigation should still be possible.
Then, the two main usages can be irrigation and transportation according to
your explanations

Am I wrong?
