Wildlife officials in Nevada are trying to determine why an estimated 100,000 trout, bass and catfish have died over the past month in a 15-year-old fishery.

Since then, they’ve been unable to detect any live fish in the 77-acre lake. Numerous dead fish have been removed from the lake’s shoreline, and Healy said it’s likely the rest sank to the bottom.
