State public health officials have lifted a health advisory that warned people of possible toxins from high levels of blue-green algae in Lost Creek Lake.
The advisory at the reservoir on the Rogue River about 30 miles northeast of Medford went into effect June 20.
Lake samples taken June 14 showed that water at the Catfish Cove day-use area sported levels of the toxin-producing anabaena flos-aquae at more than seven times World Health Organization thresholds for safety. However, water sampled at the Takelma boat ramp area at the reservoir's southwest side sported levels of the algae well below unhealthy standards, according to test results from the U.S. Army Corps of Engineers.
Continued water monitoring has confirmed reduced levels of the blue-green algae that can produce toxins harmful to humans and animals.
