The 2011 bloom season extended from June into February, 2012. Eighteen advisories were issued that were in effect for a total of 1,175 days (advisory-days). This was the first season that had an added requirement to test for both cell counts and toxins before an advisory could be lifted. Get complete details in the 2011 Bloom Season Recap (pdf).
