Hot, Dry Weather Boosts Likelihood of Blue-Green Algae in Kansas Lakes, Ponds

K-State Specialists Issue New Fact Sheet, Review Steps for Proper Testing
Posted on Jul. 13th, 2012
MANHATTAN, Kan. – This summer’s searing heat is causing a host of problems for landowners, including the threat of toxic cyanobacteria, also known as blue-green algae, on lakes and ponds.  

“Blue-green algae can sicken or kill livestock and other animals, and also poses a threat to humans,” said Kansas State University research assistant professor in agronomy, Carol Blocksome.

“If blue-green algae are suspected, a water sample can be collected and sent to the Kansas State Veterinary Diagnostic Laboratory.” 

Blocksome, who is a range management specialist with K-State Research and Extension, collaborated with K-State colleagues Deon van der Merwe and Larry Hollis to produce a fact sheet, “Identification and Management of Blue-green Algae in Farm Ponds” http://www.ksre.ksu.edu/library/h20ql2/mf3065.pdf

Van der Merwe is a veterinary toxicologist with K-State’s College of Veterinary Medicine and Larry Hollis is a beef veterinarian with K-State Research and Extension.  

Some of the tips in the fact sheet include: 

  • Take a sample where the algae is more likely to be present, such as the downwind side of a pond, and shallow areas that are warmer. 
  • Choose a clean container with a wide mouth. Rinse out the container with the pond water. Label the outside with the date and location. 
  • Scoop the water from the surface along with the scum. Be careful not to come into contact with the water by using a cup attached to a long stick, or by using gloves. 
  • Secure the lid, and put the sample into a plastic bag. Put the sample into a cooler with an ice pack, but don't freeze. 
  • Place the sample in a refrigerator, and then mail it by overnight express to the lab of choice. One option is the Kansas State Veterinary Diagnostic Laboratory, Mosier D-117, 1800 Denison Ave., Manhattan, KS. 66506-5601.
