Description
- Abstract: Long-term public health monitoring for potentially toxigenic cyanobacteria (blue-green algae) in
Tenmile Lakes has occurred since 2002 (Kann 2008; Kann 2010; Jacoby and Kann 2007). Tenmile
Lakes were again sampled in 2010 to assess the dynamics of potentially toxic blue-green algal species,
including Microcystis aeruginosa, Gloeotrichia echinulata, and various Anabaena species.
Microcystis and Gloeotrichia can produce hepatotoxins (known as microcystins), and Anabaena
produces both neurotoxins (anatoxin-a) and microcystins. Both toxins are capable of harmful effects
to animals and humans (Chorus and Bartram 1999). A toxic bloom of M. aeruginosa was first
documented in Tenmile Lakes in September of 1997, prompting the Oregon Department of Health to
issue a health advisory recommending that the lakes not be used for drinking water (numerous private
homes around the lakes utilize treated lake water for potable purposes) and that contact recreation be
avoided (Kann and Gilroy 1997). The goal of the 2010 sampling, performed by the Tenmile Lakes
Basin Partnership, was to determine presence and cell density of these potentially toxic species at a
limited number of sampling stations. Cell density of potentially toxigenic species was then compared
to drinking water guidance levels for lakes and reservoirs (e.g., Yoo et al. 1995; Chorus and Bartram
1999), as well as State of Oregon recreational guideline values (Oregon DHS 2009; Stone and Bress
2007).
