Officials are urging people recreating on the Trinity River to exercise caution after a dog’s recent death led to the discovery of a harmful algal bloom on the river.
According to the State Water Resources Control Board, staff responded to a report of a potential toxic-algae related dog death and collected samples July 7 at the Hlel-Din river access site and confirmed that “toxic algal mats” of Cyanobacteria, commonly known as blue-green algae, are growing on the bottom of the river.
“Because children and dogs are most susceptible to serious health impacts from HABs, it is recommended that they avoid touching any suspicious-looking algal material found in the water or along riverbanks,” the agency advised in a press release. “Trinity County has posted ‘Toxic Algae Alert’ and ‘Caution’ signage at recreational areas along Trinity River, including swimming access areas downstream of the bloom. Boaters and recreational users are urged to be alert when recreating in the water.”
