Assuming verical cliff walls surrounding the dead sea and digging a canal to it would lower world sea levels by ~1.95mm - in reality would be a lot more (810sq km surface area, 422m below "sea" level), doing likewise with the Caspian sea (28 metres below "sea" level and >300,000sq km surface area) would drop world sea levels by ~6cm.
That basin has a trough of around 155m below sea level - in Djibouti (neighbouring Ethiopia) I believe - only 125m in Ethiopia. I assume the area would be huge, maybe get a couple dozen cm of respite with that...
