She says officials are trying to determine what caused the oxygen levels to drop.

Other fish kill events and background data on the N.C. Department of Water Quality
In 1996 the DWQ Environmental Sciences Section (ESS), in consultation with Regional Office staff, Wildlife Resources biologists, and Division of Marine Fisheries personnel instituted a new fish kill investigation procedure to be used by the DWQ Regional Offices and other agencies to collect and track information on fish kills throughout the state. Fish kill and fish health data are recorded on a standardized form and sent to the Division's ESS where the data are reviewed.
Fish kill events happen on an annual basis and are tracked by the N.C. Division of Water Quality. A current account of fish kill events and historic data can be found below.
