Oil from spill spreads to lake
Oil from the ruptured well in the Gulf of Mexico is seeping into Lake Pontchartrain, north of New Orleans, threatening another environmental disaster for the huge body of water which was rescued from pollution in the 1990s.
Tar balls and an oil sheen pushed by strong winds from faraway Hurricane Alex slipped past lines of barges which were supposed to block the passes connecting the Gulf of Mexico to the lake.
