Cyanobacteria blooms at Round Lake and Lacamas Lake in Camas have dissipated, according to Clark County Public Health.
The agency said Tuesday morning that it has lifted blue-green algae advisories at both lakes. Public Health removed the warning advisory at Lacamas Lake earlier this month after test results from water samples showed toxin levels were no longer elevated. The advisory at Round Lake remained in place until the bloom dissipated this week.
Warning signs posted at the lakes are being removed, Public Health said in a statement. Educational signs about blue-green algae will remain year-round at the lakes and other bodies of water in Clark County known to have algal blooms. Public Health encourages people visiting lakes to watch for floating blue-green-colored scum and avoid direct contact with water in those areas.
Public Health has concluded its routine monitoring of Clark County waters and swim beaches for this season. Monitoring will resume after Memorial Day.
The agency relies on public notifications of potential algae blooms. Reports of algae blooms can be submitted on the Public Health website.
