Weather and other factors may play roles in why mysterious changes in color, sometimes overnight, occur on oceans, rivers and other waterways.
A Chinese river changed colors overnight in mid-July, prompting a government investigation into why the river in Wenzhou turned blood red.
Government officials said there was no sign of environmental pollution from nearby factories, the Voice of America reported.
However, they didn't rule out environmental pollution as the reason for the sudden color change, according to the China News website.
It wasn't the first time a Chinese river mysteriously turned red.
Illegal dumping caused the Yangtze River in Chongquing to turn red in 2012, the Associated Press reported.
Heavy rains can also cause rivers and streams to change color, AccuWeather Senior Meteorologist Dan Pydynowski said.
"It would lead to runoff of sediment, which would be more of a reddish brown color," Pydynowski said.
Increased water temperatures also play a role in developing algae blooms that can cause water to turn brown or red.
The Sanibel-Captiva Conservation Foundation staff found discolored waters in the mangroves east of Tarpon Bay, Fla., on Aug. 4, 2011. The bloom of Fibrocapsa japonica occurs in coastal waters and has caused major fish kills around the world. Outside of Florida waters, the organism has been known to produce brevetoxins, the same toxins produced by the Florida red tide organism, Karenia brevis. No adverse impacts were reported from this bloom. (Photo/Sanibel-Captiva Conservation Foundation)
