Wednesday was supposed to be the deadline for officials from Georgia, Alabama and Florida to reach an agreement about sharing water from the Chattahoochee River.
However, the confidential talks have been extended through January 31st.
Governor Perdue's Spokesman Bert Brantley said Tuesday that Georgia officials are pleased with the talks so far.
This is the second extension for the current talks. The first deadline was August 3rd.
A federal judge in Alabama ordered the three states into closed-door deliberations last April. That was nearly three years after talks sanctioned by Congress broke down. Those tri-state discussions lasted five years before the sides decided they were too far apart to continue.
The so-called tri-state water wars began about 16 years ago when Alabama and Florida took Georgia to court to stop metro Atlanta from taking too much water.
The Chattahoochee River flows through Lake Lanier. It is the main water supply for about three million people in metro Atlanta.
