CARY, N.C. (WTVD) -- The Lake at Bond Park in Cary had blue-green algae blooms in May but officials said they were tested and not producing toxins known to be harmful to dogs.
The algae blooms were observed on May 27 but analysis showed toxins were not present at the time of sampling.
Officials said sampling for algae was done again on June 13 but cyanobacteria were no longer present.
Cyanobacteria found in the blue-green algae is toxic -- dogs and children are most susceptible.
Last week, three North Carolina dogs died after playing around in a neighborhood pond containing blue-green algae.
Cyanobacteria multiplies and blooms when water is warm, stagnant and filled with nutrients from fertilizer runoff or septic tank overflows.
