Covering canals with something to slow water evaporation is a no-brainer, right? (Or should be.) How about making those covers be solar panels for a two-fer—as apparently is already happening in India—now, that’s outright ingenious.
(Incidently, I can recommend Paolo Bacigalupi’s novel The Water Knife from 2015, in which water rights and covered canals feature strongly. In case you’re interested in that sort of fiction.)
