Dead Fish Mystery

In honor of my son, an article about animals...

Article: Government officials in Northern Nevada are trying to figure out why all the fish in a man-made lake have died. An estimated 100,000 trout, bass and catfish have died in one month, but the likely number is closer to 1 million adult fish. They don't know why the sudden extinction. Some possible explanations: an unexplained drop in oxygen levels; a bitter cold that caused the lake to be too cold for the fish and sucked up additional oxygen. They think 3,000 fish died from low oxygen levels in one part of the lake but they don't know why all the fish in the lake have died. The lake was used as a fishery to stock fish; it opened in 2000 along with a bike trail, beaches, playgrounds and a fishing pier. Previously, a nearby pit had been contaminated by pollutants leaking from a nearby company tank farm, but officials say that the pollutants were all cleaned up by 1997. So far there are no plans to restock the fishery.
