CyanoAlert – Cylindrospermopsis in Lake Texoma

31 August 2011

Very little in the press today:

The blue-green algae bloom at Lake Texoma is dominated by a type of the toxin-producing algae called Cylindrospermopsis. This is a real nasty and the type of blue-green algae bloom does not look like other BGA blooms that form mats, scum, foam, or have the characteristic “spilled paint” look.  Cylindrospermopsis, like the dinoflagellate Ceratium hirundinella, is an alga that is becoming increasingly prevalent worldwide, perhaps in response to changes in salinity and climate.  Caution is always the best protection with this beast as there are very few laboratories set up to analyze for the toxin cylindrospermopsin.

In Tulsa, Oklahoma — blue-green algae could ruin the Labour Day holiday weekend for folks headed to local lakes.  The sickening blue-green algal  slime is making many places off-limits for swimming.  At Keystone Lake‘s Appalachia Bay, gate attendants Orville and Pauline Nichols are spreading the word about a spreading threat.

In Canada,  the Ottawa County Health Department is sending out a warning about Lake Macatawa Beach at Holland State Park.  There’s a blue-green algae bloom in the water there, and officials say you should try to avoid areas where that algae is present.  In the Kawartha Lakes District the local health unit lifted a water use advisory Thursday that had been issued for a section of Sturgeon Lake after confirmation that the blue-green algae bloom in that area has diminished.

From Australia, there is a massive bloom of Trichodesmium around the Great Barrier Reef.  This is a natural phenomenon, first observed in the 1700s.  Trichodesmium is  a form of cyanobacteria, are small, usually single-celled organisms that grow in the ocean and produce food through photosynthesis like plants.

    I was wondering if you could give me the name of the algae that bloomed in Lake Macatawa this past August.
