Although less common than Salmonella or Campylobacter, Shigella is a significant cause of foodborne disease. Shigella is responsible for 10% to 20% of cases of bacterial foodborne illness each year in the United States.
A century later, it continues to be a marvel in modern engineering. The LA Aqueduct brought water from the Owens Valley hundreds of miles away to a growing area in need of additional resources to sustain its people and their endeavors, helping spur an economy that today rivals that of many nations.
During dry years the project could yield 150,000 acre-feet that would be pumped out of the aquifer and piped to the aqueduct. The dam is huge: 710 feet high, 1,560 feet wide and storing 27 million acre-feet of water in Lake Powell, which extends back up the river for 186 miles.
