I guess 32.7 meters above sea level is reasonably uphill.
I'm too lazy to calculate the approximate volume of fresh water that represents, based on the lake's surface area. Pretty safe to say that the rest of the lake's volume, at and below sea level wouldn't be rendered brackish too easily.
Although, given China's penchant for environmental accidents, I wouldn't put it past them, if all that additional lake water above sea level were to get skimmed off the top by an accidental spill into the ocean.
