Deer did not die because of blue-green algae

11 August 2012

Although cyanotoxins have been excluded as a cause of death, experts have still to come up with an answer to what type of toxin, if indeed it was, killed eight deer in Oklahoma earlier this week.  This mystery has some similar echoes to the dog deaths at Sandringham during the past couple of years.

Kansas have added Johnson LakeCentral Park Lake (Topeka) and Antioch Park Lake (Merriam) to their list of lakes under warnings because of the presence of blue-green algae.  In Maryland, Horn Pond has been added to their list of problematical waters.

In Massachusetts there is an algal bloom in the Charles River at Waltham, as well as at Weston and Newton.  Massachusetts now, like Kansas, has about twelve lakes under advisories, including Crystal Lake, now closed for two weeks so far.

Veterinarians in Oregon have issued a warning to dog owners to take care when allowing their dogs to swim in lakes and ponds.  In California, a warning has been issued for not-so-Clearlake.

In Olympics Land (and, WOW, have the Brits not done a first class job of putting together the 2012 games?) – toxic algae have been found in Wivenhoe Pit in Essex.  Staying in the UK, there is an interesting story from Dartmouth, where a hovercraft is apparently being used for algal surveys in estuaries! – but in there too is an appeal for better effluent treatment and ridding detergents of phosphorus.

And, finally, in India, high levels of sustained eutrophication have seriously impaired conditions in Nigeen Lake.
