Public Health lifts algae advisory at Lacamas Lake

As summer fades and the heat dwindles, Clark County Public Health has lifted the algae advisory at Lacamas Lake.

Algae blooms, often worsened by warm weather, contain the presence of cyanobacteria or blue-green algae. Earlier in July, Public Health posted warnings around various lakes, urging the public to avoid swimming or ingesting the water. But recent water samples collected by Public Health show water quality has improved and toxin levels are not as elevated as they were in July. The county monitors popular swim areas at Vancouver Lake, Klineline Pond, Battle Ground Lake and Lacamas Lake.

Marissa Armstrong, communications program coordinator, says toxin levels may be subject to change. Public Health will continue to monitor Lacamas Lake and collect weekly water samples to test toxin levels.

Public Health says people swimming and recreating at the lake should be on the lookout for floating scum and avoid direct contact with water in areas where scum is present. Pets, children and adults should not drink or come into contact with water where there is floating scum.
