Lake Update
As we’ve seen in past years toward the end of the boating season, changing lake conditions can lead to harmful algal blooms.
The California State Water Resources Control Board has issued a warning level advisory for Big Bear Lake after harmful algal blooms were confirmed. These blooms can shift quickly with wind and water movement, so the public should assume HAB conditions may be present lake wide for now. Advisory signs will be posted at various locations around the lake.
The lake remains open.
This is a temporary advisory being issued as a precaution to protect public and pet health. The District will continue to share updates as conditions change and more information becomes available.
When in doubt, stay out.
