A resident of South Yaamba, near Rockhampton in central Queensland, has reported seeing hundreds of dead fish in the Fitzroy River.
Sharon Meehan says large barramundi and catfish that could be decades old are turning up on the river banks.
Ms Meehan says she is concerned about the water quality because her cattle drink it and her family showers in it.
She says she has spoken to the Rockhampton council about her concerns.
