I'd think you could recapture a lot of the energy as it drained right? Proposed solutions involve a lot of pumping and seem to rely on it. Hydroelectric efficiency is over 90%. The salt water would be largely contained so I'm not sure why it would be so bad for the ecosystem. I don't doubt it would be very expensive, everything about that canal has been. But if this turns out to be the new normal, rather than just a weather abberation, it will be cheaper than re-reouting all of those ships, whether the pumping is done with fresh or salt water.
