SEATTLE -- Park officials have closed Green Lake to wading, swimming and wet-water boating activities like sail boating due to a toxic algae bloom.

Seattle Parks and Recreation Acting Superintendent Christopher Williams said the lake is closed to these activities due to the presence of a cyanobacterial toxin that exceeds the Department of Health's guidelines.

Parks officials also warn dog owners not to let their dogs drink from the lake.

Rather than risk the health of any park user, we're closing the lake to some activities until we have confirmation that the water is safe, Williams said in a press release. The level of toxicity leads us to err on the side of caution to limit the risk of anyone ingesting the water.

The lake is open to fishing and boating - activities where users are unlikely to ingest the water.

Officials say the closure will be in effect until the algae bloom completes its life cycle, which could likely be weeks or months, depending on the fall weather affects the algae bloom. Dry weather typically continues the bloom.
