In the 1980's Saudi Arabia looked into using ocean tugboats to tow glacial icebergs to their shores as a new supply of fresh water. It was feasible but not economical.
In the 1990's some south-western US developers suggested piping great lakes water to Arizona & Nevada so they could develop some inexpensive desert land holdings. Some great lakes states studied the proposal and found the bad results from taking too much water out of the Colorado river. To protect their lakes, all the US states bordering the great lakes states have signed an agreement requiring that any water diverted from the great lakes must now be returned to the great lakes watershed after its use.
Some times it's most economical to store excess water in place until it's needed later.
