• Swimming or water skiing not advised anywhere on lake. 
•  Avoid areas of scum when using motorized boats, paddle boarding, kayaking or canoeing. 
• Do not drink lake water. 
• Animals should avoid all water contact.  
• When fishing, clean fish well and discard organs. 

Next Sampling Dates

• E.coli (bacteria): May 2025
• Harmful Algae (cyanobacteria): November 12th, 2024

Heavy rain the past week has dispersed the algae bloom in Lacamas Lake at Heritage Park, however the advisory remains in place.

In order to remove an algae advisory, toxicity must be below threshold for 2 consecutive weeks. If water quality continues to improve and toxicity is below threshold during the next round of sampling, the Warning Advisory will be removed.

No other blooms have been observed or reported in Clark County.
