Sandra Clinton discusses Lake Norman algae blooms with WFAE
Sandra Clinton, research associate professor in the Department of Earth, Environmental and Geographical Sciences, was interviewed by WFAE for ‘Algae blooms in Lake Norman, threaten local ecosystems.’
According to the North Carolina Division of Water Resources, more than 80 algal blooms on Lake Norman have been reported since the beginning of June.
The bright green, deep red and milky blue algae bloomed due to warm water temperatures and fertilizer runoff. As some of the algae emits toxins that are dangerous to people and wildlife, a No Swim Advisory was issued for part of the lake.
“Often when we talk about the harmful algal blooms, or toxic algae, we’re talking about the cyanobacteria,” said Clinton. “Some of these cyanobacteria make what we call cytotoxins. They can be harmful… when they’re high in concentration.”
Both toxic and nontoxic algae disrupt the ecosystem by decreasing oxygen in the water and leading to the death of fish species. Residents and visitors of the lake should not swim near the algae and should avoid letting pets near the water.
