LAKE MEAD NATIONAL RECREATION AREA, Nev. (AP) - The National Park Service says biologists are trying to determine the cause of a Lake Mohave fish die-off that has left dead carp on beaches.
Nevada and Arizona fish and game officials also have collected specimens, and test results are due back next week.
The Park Service says Memorial Day weekend visitors may encounter an unpleasant stench along the shoreline of the Colorado River reservoir behind Davis Dam north of Laughlin and Bullhead City, Ariz.
Officials say there are no known human heath risks, but are advising people to avoid handling the dead fish.
The Park Service says there haven't been any reports of similar carp deaths in Lake Mead, or of other fish species being affected.
