1) It doesn't rain any more. We're 18 inches down on where we should be for the year. Streams and rivers entering the lake are headed for record lows.
2) The more the lake drops, the faster it drops. The lake isn't shaped like a bath, but more like a funnel, with the old Chattahoochee River at the bottom. So, to drop the first 10 feet, the lake has to lose a lot of water. To lose the next 10 feet, the lake has to lose much less water.
3) Sturgeons, the purple bankclimber mussel and the fat three ridge mussel. The Corps is legally obliged to send enough water down to the Apalachicola River to keep their habitat alive. Because of this, and increased demand for drinking water, the Corps is releasing 2 to 3 times more water now than during past droughts
4) The Corps and its mistakes. Remember the faulty gauge last year? The amount of water mistakenly drained would have been enough to support Atlanta for 118 days.
5) Us. The typical North Georgian uses between 70 and 90 gallons of water per day at home, averaged throughout the year, but usage is 30 percent to 50 percent higher in the summer months. There's too many of us, using too much water
