DECATUR, Ind. (AP) _ State environmental officials are investigating what killed an undetermined number of fish in a portion of the Wabash River in northeastern Indiana.
Crews with Indiana's environmental and health agencies took water samples Wednesday from the river in Adams County for their investigation.
The Decatur Daily Democrat reports the river has a greenish cast, leading to concern that algae bloom toxins could be responsible for the fish kill.
The Indiana Department of Environmental Management's on-scene coordinator, David Cage, says toxins released from a green algae bloom in the river are a possible cause of the kill. He urged residents to avoid contact with the river water until the cause is known.
Cage says water tests show ammonia nitrates, oxygen levels and pH levels didn't contribute to the fish kill.
