Click on the balloon to see a graph of the cell counts and toxin level for that location. Annual cell count and toxin levels are available under the Graphs tab.
About the TrackerThe Tracker was built to better inform the public and research community regarding river conditions. The Tracker utilizes up-to-date multi-agency data to track the blue-green algae bloom throughout the Klamath Basin. Having trouble? The tracker doesn't work well on older versions of Explorer. Try this LINK.Blue-Green AlgaeIn the Klamath Basin blue-green algae blooms typically occur between June and October when temperatures rise and water conditions are favorable for algal growth. In an effort to protect public health, blue-green algae monitoring typically occurs May - November. If river conditions exceed public health standards for toxic algae the area is posted with a health advisory sign. The Blue-Green Algae Tracker (below) identifies blue-green algae monitoring results by location: "green" balloon = below public health threshold; "red" balloon = above public health threshold. *Posting Guidelines - Updated July 2010 - Report (pdf)The California State Water Resources Control Board (SWRCB), California Department of Public Health (CDPH), California's Office of Environmental Health and Hazard Assessment (OEHHA), and Oregon Department of Health Services (ODHS) provide guidelines for posting advisories in recreation waters. These guidelines were developed using information provided in World Health Organization. Both SWRCB and ODHS recommend posting advisories in recreation waters under four circumstances: (1) if "scum is present associated with toxigenic species"; (2) if scum is not present, but the density of Microcystis or Planktothrix is 40,000 cells/ml or greater; (3) if scum is not present, but the density of all potentially toxigenic BGA is 100,000 cells/ml or greater; and (4) If the concentration of total microcystin is greater or equal to 8 ppb or if anatoxin-a is detected. Posting Removal Guidelines - Updated July 2010This general approach may be useful in determining when to lift warning advisories: • If posting occurred due to visible scum – wait two weeks (there should be no visible scum recurrence during this time) before lifting the advisory. • If posting occurred due to exceeding a cell count guideline – wait two weeks after cell count falls below the recommended guideline (there should be no visible scum recurrence during this time) before lifting the advisory. • If posting occurred due to exceeding a toxin concentration guideline – wait 1 week after the toxin concentration falls below the recommended guideline (there should be no visible scum recurrence during this time) before lifting the advisory. About Blue-Green AlgaeBlue-green algae (cyanobacteria) are a form of bacteria. Surface scums of blue-green algae are common in the summer months within reservoirs and along the Klamath River. Exposure to blue-green algae can cause rashes, skin and eye irritation, allergic reactions, gastrointestinal upset, and other effects. At high levels, exposure can result in serious illness or death. Small children and dogs are particularly susceptible due to their small body size and their potential to ingest water while recreating.In an effort to better inform the public and tribal communities regarding the current locations and toxicity levels of blue-green algae blooms, members of the Klamath Basin Monitoring Program have developed the "Blue-green Algae Tracker" providing direct access to the most up-to-date monitoring data from the current monitoring season. The "Blue-green Algae Tracker" will eventually include historic data dating back to 2005.

The role to the editorial board is to review articles for submission to the Klamath Current. The editorial board reviews submissions based on content and ability to enhance the understanding of water quality issues facing the Klamath Basin. The editorial board is comprised of four KBMP members, representing the broad interests of the KBMP membership.
