Results from water samples taken from Lacamas Lake on Monday, June 2 revealed toxin levels above the threshold levels recommended by the Washington Department of Health
VANCOUVER – Clark County Public Health has issued a warning advisory at Lacamas Lake due to elevated levels of cyanotoxins from harmful algae.
Results from water samples taken from Lacamas Lake on Monday, June 2 revealed toxin levels 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. While the warning advisory is in place, Public Health recommends:
- No swimming.
- No water contact for animals.
- Avoiding areas of scum when using motorized boats, paddle boarding, kayaking or canoeing.
- No drinking lake water.
- Cleaning fish well and discarding organs.
Public Health will continue to monitor Lacamas Lake and, while blooms are present, take weekly water samples to test toxin levels. Signs will be updated as conditions change.
Public Health is also monitoring Round Lake in Camas and Vancouver Lake for algae blooms. Small algae blooms were present at Round Lake on Monday, but results from water samples indicate toxin levels were low. And algae were dispersed in the water at Vancouver Lake on Monday, but a bloom has not developed.
Harmful algal blooms can develop and toxin levels can change as conditions at the lakes change. Public Health encourages people swimming and recreating in the lake to watch for floating scum and avoid direct contact with water in those areas.
Harmful algal blooms can pose a significant health risk if the cyanobacteria or toxins are ingested, inhaled or contact skin. Inhaled bacteria or toxins could cause wheezing, coughing, chest tightness and shortness of breath. Skin contact could lead to rash, itching, blisters and eye irritation.
If water with cyanotoxins is accidentally swallowed, symptoms could include abdominal pain, diarrhea, vomiting, numbness of the lips, tingling in fingers and toes, and dizziness.
Additional information about harmful algal blooms and current advisories are posted on the Public Health website. To report algal blooms in other bodies of water, visit the Public Health website.

Right on time for warm weather. This is an annual event. The lake is closed before it ever opens for any recreation.
I’m pretty sure a major contributor to this is the fertilizer runoff from all of the mini-mansions that have been built around the lake on it’s watershed. Hard to see any other major cause for this. Same thing happens to Vancouver Lake.
