The San Antonio Flood of 1998

Olmos Dam

Last Index Next

This is not the first time San Antonio has been inundated. Beginning in 1913 the community endured six floods in nine years. In response the city built Olmos Dam pictured here. Usually it has no water behind it, but as you can see, water is only a few feet below the the spillway at the far end.
To keep the dam from overflowing, the floodgates had to be opened. This is from the top of the structure.
The gates had to be opened by hand since electricity had been cut off in that part of town.
