Doesn’t scratch the itch, but I will concede that this is a fair point

If you want to do a megaproject, just cover a significant amount of the lake in reflective material. This will reduce evaporation, increasing the lake level. It would be very bad for the ecosystem, though, since it depends on sunlight.

Sounds like the northern part of the lake doesn't have much of an ecosystem anyway, so why not start there?
