The 2010 bloom season extended from April into January, 2011. Twenty-two advisories were issued that were in effect for a total of 1,412 days (advisory-days). The number of advisories increased from six in 2005 to 22 in 2010. The increase may indicate that cyanobacteria blooms are increasing in severity but may also reflect enhanced surveillance efforts among local, state and federal partners.
