Health alert issued for toxic algae in Snake River

SNAKE RIVER, Idaho (CBS 2) — A health alert has been issued for toxic algae along a 15 mile stretch of the Snake River. The impacted area begins at the BLM’s Canyon Creek/Swede’s Landing area and runs to Idaho Power’s Woodhead Park.

Recent samples taken from the water body indicate high concentrations of toxin-producing cyanobacteria – better known as toxic algae -- which can be harmful to people, pets, and livestock. Those with liver or kidney damage are at an increased risk of illness.

Toxic algae blooms are not unusual this time of year when water temperatures rise. The public will be advised when it is likely the concern no longer exists.

When recreating near or in Brownlee Reservoir, take the following precautions while the advisory is in effect:

• Avoid swimming, wading, or other activities. Take extra precautions to ensure children, pets, and livestock are not exposed to the water.
• Do not drink or cook with water containing a bloom. Boiling and filtering the water can increase the risk.
• Wash your hands thoroughly after handling fish caught in water experiencing a bloom. Cyanotoxins can accumulate in fish and the risk to people is being researched. Any fish caught should be cleaned and washed thoroughly in uncontaminated water and any internal organs disposed of before consumption. If people choose to eat fish from this area, filet the fish and remove all of the fat, skin, and organs before cooking.
• Clean with potable water as soon as possible if water contacts skin or pet fur.

Symptoms of cyanotoxin exposure include rashes, hives, diarrhea, vomiting, coughing, and/or wheezing. More severe symptoms affecting the liver and nervous system may result from ingesting water. If symptoms persist, consult your healthcare provider.

Southwest (ID) District Health, Idaho Power, and the Idaho Department of Environmental Quality (DEQ) have issued a health advisory for 15 river miles of Brownlee Reservoir on the Snake River from the Vle BLM’s Canyon Creek/Swede’s Landing area to Idaho Power’s Woodhead Park, urging residents to use caution when recreating in or near the water.
