REPORT AN ALGAE BLOOM

If you see a suspected algae bloom take a photo and describe what you see and where and contact us (King County, and Ames Lake Community Club Board) and we can coordinate the best way to get a sample to the lab.

Normally algae blooms are not toxic but there is no way to know for sure without testing so please take appropriate level of caution and if you see something, report it so it can be tested!

In general...for you and your pets

Avoid contact with algae. Avoid swallowing water while swimming. Take a bath or shower with warm soapy water after coming in contact with lake water.


How can you help prevent algae blooms

2021 WATER TESTING REPORT

The key takeaways from the 2021 monitoring season are:

 

• Ames Lake continued to have fairly clear water, with low nutrient concentrations and algal growth.

• An algal bloom was sampled for toxin testing in May and June. Toxin testing found microcystin and anatoxin present in the June samples, at concentrations well below the Washington State Recreational Guidelines.

2020 WATER TESTING REPORT

The key takeaways from the 2020 monitoring season are: 

  • Ames Lake continued to have fairly clear water, with low nutrient concentrations and algal growth. 

  • An algal bloom was sampled for toxin testing in August 2020. No algal toxins were detected in the samples.

  • "Nitrogen-to-phosphorus (N:P) ratios were above 25 for most of the monitoring season. This indicates a low likelihood for the algal community to be dominated by cyanobacteria (which have the ability to produce toxins)."
