Ended… Blue-Green Algae bloom found on Charlie Lake…

This story is currently NOT in effect and is from 2016! For some reason it has been dug up and shared countless times on April 16, 2021.


FORT ST. JOHN, BC: A blue-green algae (cyanobacteria) bloom is suspected in various Northern BC lakes, including Charlie Lake, therefore, Northern Health has issued an Advisory to stay out of the lake until further notice. Below is a list of Northern BC lakes affected by the Blue-Green algae blooms…
Current lakes under the advisory include:

  • Charlie Lake (Fort St.John)
  • Bednesti/Berman Lakes (Prince George)
  • Nulki Lake (Prince George)
  • West Lake (Prince George)

Residents living near the shores of these lakes, as well as visitors to these lakes, are advised to take the following precautions:

  • Avoid all contact will blue-green algae blooms. If contact occurs, wash with tap water as soon as possible
  • Do not swim or wade (or allow your pets to swim or wade) in any areas where blue-green algae is visible.
  • You can safely consume fish fillets from this lake, but should limit your consumption of whole fish and trimmings as fish may store toxins in organs such as the brain, liver and intestines. Pets should avoid eating whole fish and trimmings.
  • As always, visitors and residents are reminded to never drink or cook with untreated water taken directly from any lake at any time. Boiling lake water will not remove the toxins produced by blue-green algae. An alternate source of drinking water should also be provided for pets and livestock, while this advisory is active.

Persons experiencing illness after having contact with lake water are advised to seek medical attention.

Below is detailed information from the BC Government on Blue-Green Algae…

What are blue-green algae?

Blue-green algae, (also known as Cyanobacteria), are bacteria that grow in shallow, slow moving or still water. This includes fresh water lakes, ponds or wetlands. Blue-green algae can range in colour from olive-green to red.

What are blue-green algae blooms?

When the amount of blue-green algae increase a lot, a large, dense mass will form. This mass is called a bloom. Blooms cover the surface of the water and can look like thick pea soup, often blue-green in colour. However, not all blooms are easy to see. Toxins can still be in the water even if you cannot see the blooms.
Blue-green algae blooms occur naturally. Yet, water bodies enriched with nutrients from human activities such as municipal, industrial or agricultural sources are much more likely to have blooms.

Are these blooms poisonous?

Some blue-green algae blooms can produce chemicals that are poisonous if swallowed by people, pets, or livestock. Other blooms can have no noticeable effect on pets or livestock.
There are 2 types of toxins or poisons that can be produced by blue-green algae:

  • Neurotoxins: Affect the nervous and respiratory systems and can cause muscle tremors, stupor, staggering, rapid paralysis, breathing problems and, in extreme cases, death (mostly observed in livestock). Pets and livestock that die from this are usually found close to the body of water where they drank from.
  • Hepatotoxins: Affect the liver and can take days before symptoms appear after drinking affected water. Pets or livestock that get sick after drinking enough of this toxin may show jaundice (yellowing of the white of the eye, and sensitivity to sunlight).

How could I be exposed to blue-green algae?

You can be exposed to blue-green algae by drinking water that has blue-green algae in it, or by doing recreational activities such as swimming, boating or waterskiing in water with blue-green algae.
During a severe blue-green algae bloom, water looks bad, and may also smell bad. Adults or older children will likely not drink this water. However, younger children may be less careful, or unaware of the dangers of drinking water with blue-green algae blooms.

What are the symptoms of exposure to blue-green algae?

Symptoms from drinking water that contain blue-green algae can include: headaches, nausea, fever, sore throat, dizziness, stomach cramps, diarrhea, abdominal pain, vomiting, muscle aches, mouth ulcers, and blistering of the lips. Symptoms from swimming and other recreational water activities in contaminated water can include skin rashes and irritated ears and eyes.
If you have been exposed to blue-green algae toxins and have any of these symptoms, rinse off your body and see your health care provider right away.

How are pets and livestock exposed to blue-green algae?

Pets and livestock with no other source of drinking water may be poisoned by drinking contaminated water with blue-green algae. To reduce risk to livestock, do not allow rainwater or other surface runoff to flow through livestock areas.

How long does a bloom last?

Blooms may last for weeks, months, or possibly all year. If you are unsure about the quality of the water, contact your local Ministry of Environment regional office.

How can I prevent illness from blue-green algae?

To prevent illness from blue-green algae make sure to:

  • Follow the advisories of your local Government, local Health Authority, and Ministries.
  • Never drink untreated water from lakes, ponds or wetlands. Boiling water does not remove blue-green algae from the water.
  • Never wade, swim or bathe in water with visible blooms.
  • Never cook, wash dishes, or do laundry in water heavily contaminated with blue-green algae.
  • Never let pets or livestock into the water if there are blue-green algae, and provide them with other sources of drinking water.

In addition to possible health risks from bluegreen algae, you may get sick from other illnesses spread by drinking untreated water. For more information on safe drinking water, see HealthLinkBC File #49b Disinfecting Drinking Water.

Who should I contact to report blue-green algae blooms?

If you see a blue-green algae bloom, contact the nearest public health unit or Ministry of Environment Regional office at www.env.gov.bc.ca/main/regions.html
