The court's decision Monday raises fundamental questions about
Georgia's rights to Lake Lanier, a massive federal reservoir
It could also play a key role in deciding the long-running water wars among Georgia, Florida and Alabama.
The case involves a 2003 water-sharing agreement with the Army
Corps of Engineers that would have allowed Georgia to take far more
water from Lanier for drinking water.
Florida and Alabama contested the pact.
A lower court agreed, saying the Corps didn't have authority to use the lake for that reason.
Georgia had appealed to the Supreme Court for another review.
