(Camas, WA) -- The health advisory for Lacamas Lake has been lifted. Clark County Public Health says tests show toxin levels from blue-green algae are no longer elevated. The warning signs posted at the lake have been removed. As long as algae is present, the blooms could return depending on conditions at the lake. The city of Camas recently began the annual drawdown of Lacamas Lake, and in past years, the lowered water level during the drawdown has caused water quality to deteriorate at the lake.
