Current advisories

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. Advisories are updated as conditions change. Below are the most current advisories as of today. 

For information about our sampling and advisory decisions, please view our advisory protocol.

    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.

    *Be advised that only designated swim beaches are routinely monitored by Clark County Public Health. Designated Swim Beaches are beaches that have swimming areas separated from other recreational water activities such as boating or fishing. We rely on the community to inform us of water quality concerns. Please continue to report any public health concerns that you may observe.
