Abstract: Long-term public health monitoring for potentially toxigenic cyanobacteria (blue-green algae) in Tenmile Lakes has occurred since 2002. Tenmile Lakes were again sampled in 2011 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. 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. The goal of the 2011 sampling, performed by the Tenmile Lakes Basin Partnership, was to determine presence and cell density of these potentially toxigenic 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 as well as State of Oregon recreational guideline values.

Purpose: Harmful Algae Bloom assessment.
