Current advisories

Vancouver Lake swim beach

Between Memorial Day and Labor Day, Public Health routinely monitors local designated swim beaches for bacterial contaminants and harmful algal blooms. Other water bodies are monitored if we receive reports of unsafe conditions such as sewage spill or algal bloom. If there are elevated levels of bacteria or toxins from an algal bloom, advisory signs will be posted at the lake.

Whether an advisory is in effect or not, always use caution when swimming in open water. This includes not swallowing water, entering open water with open cuts or sores, entering water that appears scummy or swimming in areas before you are familiar with the natural hazards that may exist. Please read below for information on current advisories.

Do you see a water quality safety concern?

Public Health relies on public notifications to report algae blooms. Once a report is received, weekly monitoring of the bloom will begin. Please contact us if you see any algae blooms or fecal contamination that may warrant a public health response.
