Avoid contact with blue-green algae

From the Department of Health and Human Services:

Local Public and Environmental Health officials are warning recreational users of all bodies of fresh water to avoid contact with cyanobacteria (also known as blue-green algae).

The North Coast Regional Water Quality Control Board in cooperation with the Humboldt County Department of Health & Human Services, Mendocino County Environmental Health and Lake County Public Health Division issued a warning to avoid contact with cyanobacteria and algal blooms. Although commonly referred to as blue-green algae, following the lead of the state, jurisdictions are using the term cyanobacteria as it is not algae, but bacteria.

Typically, cyanobacteria warnings come out between late July and early August, coinciding with low flows and sustained high temperatures in the inland areas which may contribute to cyanobacteria growth in the river.

Human activities have an effect on nutrient and water flows in rivers, streams and lakes. Nutrients found in fertilizers, animal waste and human waste can stimulate blooms. Excessive water diversions can also increase water temperatures and reduce flows. People can take the following measures to prevent algal blooms in our waters:

  • Be conservative with the use of water, fertilizers and pesticides on your lawn, garden or agricultural operation.
  • Avoid nutrient runoff by recycling any “spent” soil by tilling it back into gardens, or protecting it from rainfall.
  • Create shade and filter out nutrients by planting or maintaining native plants around river banks.
  • Inspect and pump out septic systems every three to four years.
  • Prevent surface water runoff from agricultural and livestock areas.
  • Prevent erosion around construction and logging operations.

Cyanobacteria can be present in any fresh water body. It looks like dark green, blue-green, black, orange or brown scum, foam or mats on the riverbed or floating on the water. Warm water and abundant nutrients can cause cyanobacteria to grow more rapidly than usual causing “blooms.” These blooms are termed “harmful algal blooms.” Most cyanobacteria does not affect animals or people, however, a small number of cyanobacteria species are capable of producing toxins that can be harmful to animals and humans. Dogs and children are most likely to be affected because of their smaller body size and tendency to stay in the water for longer periods of time.

The presence of cyanobacteria has been previously confirmed in some water bodies within Humboldt, Mendocino and Lake counties including the South Fork Eel River, Van Duzen River, Trinity River, Clear Lake and Lake Pillsbury. It is difficult to test and monitor the many lakes and miles of our local rivers. Most blooms in California contain harmless green algae, but it is important to stay safe and avoid contact.

Officials recommend the following guidelines for recreational users of freshwater areas:

  • Keep children, pets and livestock from swimming in or drinking water containing algal scums or mats.
  • Adults should also avoid wading and swimming in water containing algal blooms. Try not to swallow or inhale water spray in an algal bloom area.
  • If no algal scums or mats are visible, you should still carefully watch young children and warn them not to swallow any water.
  • Fish should be consumed only after removing the guts and liver and rinsing fillets in tap water.
  • Never drink, cook with or wash dishes with water from rivers, streams or lakes.
  • Get medical attention immediately if you think that you, your pet, or livestock might have been poisoned by cyanobacteria toxins. Be sure to tell the doctor or veterinarian about possible contact with cyanobacteria or algal blooms.
  • Join or support one of the many watershed and river organizations.

Update on Marble Fire

From Six Rivers National Forest:

The Marble Fire on the Orleans/Ukonom Ranger District has burned 280 acres as of early Friday morning according to Incident Commander Rick Young, more than doubling the acres reported yesterday. The fire is currently contained at 8%.

Assigned to this fire are:

Cooperators include the National Park Service, Karuk Tribe, California Highway Patrol, and Siskiyou County Sheriff’s office.

Fire behavior was minimal last night due to high humidity and low temperatures. Fire crews worked overnight to complete fire suppression directly along the Patterson Road on the north side of the fire and along 13N32 Road on the south. They also worked on direct suppression across the northeastern fire perimeter (moving southeast) across Stanshaw Creek.

Today, crews will pick up attempts at direct suppression across the northeastern fire edge. They will also scout opportunities for contingency lines, should they become necessary. They will be brushing and opening roads within the fire area which were impacted by winter storms.

“Safety is first for all people assigned to the Marble Fire,“ said Acting Forest Supervisor Michael Green. “Despite the challenging terrain, heavy fuels and underbrush, I expect everyone to do their jobs safely and all come home after every shift.”

Weather today is expected to be similar to yesterday, gusting up-canyon in the afternoon to approximately 15mph, and becoming down-canyon during the night. A warming, drying trend is predicted over the weekend with lower humidity recovery overnight. A chance of thunderstorms, with some potential for dry lightning, is predicted to increase into Sunday.

A voluntary evacuation advisory is still in effect for private structures near the fire area. The public is discouraged from being on Highway 96 in the fire area to allow for emergency vehicle travel.

The Six Rivers National Forest remains under fire restrictions. We encourage the responsible use of fire in all activities. To learn more about the restrictions, please visit http:www.fsusda.govsrnf/.
