Pyramid Lake Algal Bloom Advisory at “Caution”

By Maggie Macias, California Department of Water Resources

Sacramento, CA (Friday, Aug. 17 at 1:40 p.m.)—The Department of Water Resources (DWR) today lowered a warning advisory that had been in effect since July 27 at Pyramid Lake in Los Angeles County and swimming at the lake is now permitted. DWR urges all recreational users to exercise caution and avoid direct contact with blue-green algae.

DWR lowered the advisory level after detecting a reduced amount of microcystins for a second consecutive week at Pyramid Lake. Emigrant Landing and Vaquero beaches are now open to swimming.

Advisories are based on the potential health risks from algae. Exposure to toxic blue-green algae, also known as cyanobacteria, can cause eye irritation, allergic skin rash, mouth ulcers, vomiting, diarrhea, and cold- and flu-like symptoms. Pets can be especially susceptible because they tend to drink while in the water and lick their fur afterwards.

Bloom conditions can change rapidly, and wind and waves may move or concentrate the bloom into different regions of the lake. The algal bloom can accumulate into mats, and scum, form foam at the surface and along the shoreline, and range in color from blue, green, white, or brown.
State guidelines on cyanobacteria and harmful algal blooms recommend the following precautions be taken in waters impacted by blue-green algae:

  • Take care that pets and livestock do not drink the water, swim through algal blooms, scum, or mats, or lick their fur after going in the water. Rinse pets in clean water to remove algae from fur.
  • Avoid wading, swimming, or jet or water skiing in water containing algal blooms, scum, or mats.
  • Do not drink, cook, or wash dishes with untreated surface water from these areas under any circumstances. Common water purification techniques such as camping filters, tablets, and boiling do not remove toxins.
  • Do not eat mussels or other bivalves collected from these areas. Limit or avoid eating fish. If fish are consumed, remove the guts and liver and rinse filets in clean drinking water.
  • Get medical treatment immediately if you think that you, a family member, friend, pet, or livestock might have been poisoned by blue-green algae toxins. Be sure to alert medical professionals to the possible contact with blue-green algae. Also, make sure to contact the local county public health department.For more information visit:
