Clark County Public Health has lifted a health advisory for recreational use at Vancouver Lake after lab results indicate cyanobacteria — known commonly as blue-green algae — is no longer a threat to the health of people and pets.
“Even though it’s late in the season, we are pleased to announce that the lake is again open for swimming and other recreational uses,” said Dr. Alan Melnick, Clark County health officer.
Melnick still cautioned that people be observant and avoid any pockets of the lake that might have a scummy texture and a green, bluish, brownish, or reddish-green color.
Algae blooms are often caused by warm, sunny weather and the presence of nutrients such as fertilizers and agricultural, human, and animal waste.
