Early Algae Outbreak Reported at Lake Cascade

Keep your family, friends, and pets safe this summer

 

CASCADE – With deepening droughts and summer heat settling across Idaho, Friends of Lake Cascade have reported the first seasonal algal bloom in the Boulder Creek Arm Tributary.

Algal blooms can be toxic and harm humans, pets, and other wildlife. When outbreaks occur, officials recommend those recreating around Lake Cascade restrain from drinking, swimming or walking near water where an outbreak is occurring. 

“This is one of the earliest outbreaks we have seen in the area,” said Lenard Long, a Friends of Lake Cascade member. “We need to work together to reduce contaminants in our water.”

Harmful bacteria from the blooms can create toxins when conditions are right. Last week, when this outbreak was identified, the Idaho Department of Environmental Quality determined that they were not yet producing toxins. As a result, DEQ and the local health district have not yet issued a warning. However, with the upcoming holiday weekend, Idaho Conservation League would like to stress that toxins can still appear at any time during an outbreak.

“Given warming temperatures and dropping water levels, it’s likely only a matter of time,” noted Jonathan Oppenheimer, ICL’s external relations director. “In fact, this year’s algae growth is showing up one month early.”

The most common causes of algae outbreaks are excess pollutants, such as phosphorus and nitrogen, combined with warm water temperatures. Cyanobacteria is the most common form of toxic algae; it’s typically a blue-green color, but can sometimes take on a reddish-brown hue.  While not all algae outbreaks are harmful, ICL and public health officials advise the community and visitors alike to act cautiously when recreating this summer. 

Help keep your family and friends safe this summer. Keep children and pets away from algal blooms and remember to never consume untreated water. If you notice green discolored water, call and report it to DEQ at (208) 373-0570.
