 Officials issue warning for high levels of toxic 
blue-green algae

State and federal officials are now warning fishermen and swimmers to 
avoid dangerous algae blooms in the Klamath River. 

The U.S. Environmental Protection Agency and the North Coast Regional 
Water Quality Control Board said Friday that water samples from Copco 
and Iron Gate reservoirs show high levels of toxic blue-green algae, and

mats of algae have also been found as far as 125 miles below the dams
that 
create the reservoirs. 

"This algae produces toxins that pose a significant potential public
health 
concern," said EPA water division director Alexis Strauss. "We advise 
people to avoid all direct contact with Klamath River water while the 
bloom is occurring." 

The nutrient-rich Klamath River supports blue-green algae growth, as do 
the warm, calm waters of Iron Gate and Copco reservoirs. The extent of 
the blooms, and their toxicity, were not known until studies were 
conducted this year by the Karuk Tribe. 

The levels the Karuk Tribe found exceeded the World Health 
Organization standard for recreational use by as much as 468 times, said

Karuk Water Resources Coordinator Susan Corum. These levels are 
among the highest recorded in the United States, she said. 

Direct ingestion of contaminated water or accidentally swallowing the 
water while swimming can cause serious health effects, the agencies
said. 
The effects of ingesting the mycosystin toxic range from skin conditions

to permanent organ impairment and death depending on exposure. 
Children and pets are especially at risk. 

Symptoms can include mild to severe eye irritation, allergic skin rash, 
mouth ulcers, fever, cold and flu-like symptoms, vomiting, diarrhea, 
kidney damage, liver damage or complete failure, and death. 

The agencies recommend that people not drink or cook with 
contaminated water. People should avoid or minimize contact with 
contaminated waters. It is best of stay out of the water near algae
blooms 
and to keep pets away. If people do come in contact with the water, wash

thoroughly with clean water. Avoid eating fish caught during an algae 
bloom. Fishermen should clean fish with fresh water and dispose of the 
innards away from the river or where animals could eat them. Avoid 
irrigation with contaminated water. Report dead or distressed wildlife 
along the shoreline to local, state or tribal authorities.
