State environmental regulators are investigating a fish kill in a creek in Franklin County.
WSLS-TV reports that Department of Environmental Quality biologists found hundreds of dead bass, large carp and catfish this week in Gills Creek. The creek runs into Smith Mountain Lake.
The agency says heat may have been the culprit. The water temperature in the lake has risen in the past few days and the agency says that could have taken the oxygen out of the creek.
Other possible causes include contamination from farming pesticides or manure.
