Lake Clementine Cyanobacteria Alert September 3, 2021

Updated 9/3/2021:
After the recent monitoring results from Upper Lake Clementine, additional samples were collected at 5 locations along the North Fork of the American River within Auburn SRA on August 31st.  Results from the analyzed samples were received on the afternoon of September 3rd. Water samples in at Upper Lake Clementine and in the area of the boat-in campground at Lake Clementine did not detect harmful toxins associated with harmful algal blooms. However, algal mat samples collected in the Mineral Bar Campground area, at Yankee Jims/Shirttail Creek, and just downstream from the Ponderosa Bridge all detected harmful toxins. For more details please refer to the HAB Incident Map.   

Due to the variable nature of harmful toxin levels, we recommend visitors to all sections of the North Fork of the American River (Mineral Bar to Rattlesnake Bar) assume that harmful toxins are present in the river as a result of algal mats. The toxins are especially dangerous to dogs, who are more likely to ingest the toxin-producing algae. Dogs should be kept away from the north fork at all times. We have received reports of dog fatalities likely resulting from cyanobacteria ingestion in 2020 and 2021 in the Oregon Bar area of Auburn SRA.  Swimming in the river or at Lake Clementine should be done with caution to avoid the slower moving side channels where algal mats tend to grow.  We have not received any reports of harmful toxin reactions in people.


Updated 8/25/2021: 

During monitoring for the State Water Boards pre-holiday assessment, an algal mat sample was collected at Upper Lake Clementine on August 16, 2021. On August 24, 2021, State Parks received notice that a high level of anatoxin-a (99.87ug/l) was detected from the algal mat sample.  If this level were detected in the water column (planktonic) rather than directly from the algal mat (benthic), the level would result in a danger advisory which would recommend no human contact with the water.  Because the sample was taken from a cyanobacteria producing algal mat, the concentration of anatoxin is likely to overrepresent the actual level of anatoxin in the water column. We are working with the Central Valley Water Resources Board and have posted signs throughout the Lake Clementine area advising that toxic algal mats are present in the water body.  We plan to conduct additional sampling in other areas along the North Fork.  Cyanobacteria anatoxins can cause illness in people and can be fatal to dogs.  Human and animal contact with suspected algal mats should always be avoided.  More information about toxic algal mats and HAB incident reports can be found here: My Water Quality: California Harmful Algal Blooms (HABs).
