Unformatted text preview: Water Cycle Lakes Flooding What is the main difference between tap water and bottled water? What is the most important thing to filter out? Early last month, NASA announced the discovery of a microorganism that is built from arsenic. The researchers claim that this is "in part a result of Mono Lake's isolation from its sources of fresh water for 50 years." Considering fresh water is only about 3% on earth and there's a lot of toxic waste being dumped, how likely is it that other organisms like this will form? How will this affect earth overall?

Problems Associated with lake drying up? 1901: Imperial Canal brings water from the Colorado River to the Imperial Valley. 1904: Silt blocks the Imperial Canal preventing it from supplying water to the Imperial Valley. 1905: Temporary diversion of the Colorado River, constructed to replace water from the blocked canal, is breached by floodwaters. River changes course and flows into Salton Sink. 1906: Floodwaters continue to fill Salton Sea, washing away a chain of lakes along the route and threatening Imperial Valley’s fledgling agriculture industry. 1906: The Salton Sea is recorded at – 195 feet below sea level. 1907: Floodwaters continue to fill Salton Sea until in February Southern Pacific Railroad closes the river breach. So why hasn’t the Salton Sea dried up?
