LAKE COUNTY, Calif. – Officials said recent testing has indicated improved conditions in Blue Lakes, which in December tested positive for anatoxin.
The county of Lake reported that followup testing after the initial detection has been negative, so all caution signs have been removed and any restrictions have been lifted.
Initial testing in December demonstrated a low level of anatoxin (0.17 µg/l) and “Caution” signs were posted.
Further tests were conducted on Dec. 16 and Jan. 7, and both specimens showed no signs of toxin, the county reported.
Per the state’s protocol, when two consecutive tests come back negative, warning signs can be removed and usual activity can be resumed.
Conditions can change at any time, so county officials recommend continuing to watch for algae blooms, avoid contact, and report changes to Water Resources at 707-263-2344 or to Environmental Health at 707-263-1090.
The Clear Lake cyanobacteria monitoring program run by the Big Valley Band of Pomo Indians and Elem Indian Colony funded the analysis.
Their program has been routinely collecting a water sample at the Upper Blue Lakes as part of their monitoring program. Further testing will be performed in order to monitor ongoing risk.
County officials said the program has been highly beneficial to the health of our community.
For more information, the Water Board posts information about the bloom on the State Water Boards Twitter page.
