Egypt should start a megaproject

The pharoahs had huge projects such as the pyramids. Egypt has a huge population and many are in poverty. They could use the manpower to cut a channel to the depression in the Lybian desert and create an artificial lake bringing water to the parched desert area. It would get unemplyed people working and the lake stocked with saltwater fish from the Mediterranean Sea so there can be fishing. It could create a resort and also bring more wild life such as birds migrating to the lake if trees are planted around the rim. Salt could be extracted and tourism would be increased as those going to the pyramids could visit the lake.
