Mysterious brown foam and fish deaths at Lake Mead, USA
Mysterious brown foam was found floating on the Lake Mead's surface on June 9/10, 2013. Park officials urged people to avoid the Overton Arm, after several dozen carp were found dead. Nevada Department of Wildlife is investigating the fish deaths.
“Until we know for sure what is creating the foam and what is causing the fish to die, we advise people to stay out of the water in the Overton Arm just to stay on the safe side!” Christie Vanover, National Park Service spokesperson.
Unknown foamy substance was determined to be coming from the mouth of the Virgin River and spanned approximately eight miles down to Echo Bay. The Southern Nevada Water Authority is monitoring water quality at two intakes and so far hasn't found anything toxic. Southern Nevada Water Authority spokesman Bronson Mack suggests the foam may have been caused by dead algae from an increase in water temperature although the tests had determined that samples had no characteristics of any known toxic algae contamination.
