A week after Iselle slammed into Hawaii island, the state issued a brown water advisory from Cape Kumukahi lighthouse to Kalapana on Hawaii island, saying the tropical storm’s aftermath is still affecting the waters off Puna.

“Although the flood and storm water runoff may not be brown, the public is advised to stay out of inland and coastal waters in the affected areas due to possible overflowing cesspools, sewer manholes, pesticides, animal fecal matter, dead animals, pathogens, chemicals, and associated flood debris,” said the advisory issued by the Department of Health’s Clean Water Branch late Thursday.

The advisory also notes that turbid runoff may have included dead animals, which can attract sharks.
