Dogs got sick and some died after swimming near the Farrington Boat launch on Jordan Lake over the weekend, according to Chatham County Public Health.
The Department of Environmental Quality reports algae blooms and cyanobacteria, also called blue-green algae, at half a dozen monitoring sites around Jordan Lake, south of Chapel Hill.
On Monday morning, Frances Foner, of Morrisville, was putting her stand-up paddleboard in the water at the Farrington Point boat launch. She said she had not heard about the algae bloom or dogs getting sick. 
"Sometimes I bring my dog right here," she said. "We see a lot of other dogs here."
She said she feels more comfortable bringing her dog to Jordan Lake because "it’s a larger body of water and less stagnant." She avoids taking her dog to places like Lake Crabtree because she worries about algae there.
This is not the first time environmental officials have warned about toxic algae in Jordan Lake. A 2018 study from researchers at N.C. State University found low levels of toxic algae are found year-round in the lake.
But it becomes worse in the summer months when sunlight and warm water temperatures help the algae grow, according to DEQ.
"Some algae, especially blue-green algae, can produce toxins. These toxins have been linked to adverse health effects in wildlife, domestic pets, and humans," according to state environmental officials.
Lakes with toxic algae can look discolored or have scum on top that looks like "spilled paint," according to DEQ. "Blooms can appear bright green, blue, red, or brown.  As cyanobacteria in a bloom begin to die, they may produce a strong, foul odorand turn milky blue in color."
 
People can use DEQ’s algal bloom map to check algae levels in North Carolina lakes. But they should also look out for discolored water and other signs of blooms.
