Clark County Public Health issued a warning advisory at Round Lake in Camas due to elevated levels of cyanotoxins from harmful algae.

Results from water samples taken Monday from Round Lake revealed cyanotoxins above the threshold levels recommended by the Washington Department of Health. Warning signs are being placed at public access points at the lake.

"Cyanotoxins can be harmful to people, especially young children, and deadly for small pets that drink the water," Public health said in a news release states.

While the warning advisory is in place, Public Health is advising people to not swim or water ski; avoid areas of algae "scum" when boating, paddleboarding, kayaking or canoeing; avoiding drinking or exposing their animals to the lake water; and clean fish well and discard the organs.
