Keep pets away from algae in lake

a news release

Elephant Butte Lake State Park is advising dog owners to take certain precautions, following the death of a 12-pound Jack Russell terrier at Elephant Butte Lake State Park, who died after possibly ingesting naturally occurring blue-green algae in the lake. The dog had been swimming for several hours along a cove, when he became ill and later died.

"There is a suspicion that algae consumption may be to blame, though it hasn't been confirmed," said State Parks Director Dave Simon. "Until we know for sure, it's advisable to keep pets out of the water where algae are present."

Blue-green algae, or cyanobacteria, are aquatic, photosynthetic (live in the water) microscopic organisms that are naturally occurring in lakes and streams. Algae forms when conditions include the presence of warm, shallow, stagnant water that receives a lot of sunlight. Toxic algae blooms are usually localized, sporadic and last a very short amount of time, primarily in the summer.

Though not naturally a toxin, algae can produce toxins which can make animals sick when consumed, except for fish. Algae toxins have been shown to attack the nervous system of animals, which can lead to death if not immediately treated. When swimming near algae blooms, people can develop skin rashes, and might experience symptoms similar to that of food poisoning.

As is the case in any body of water at any location, algae are more prevalent (if present at all) in isolated coves during the summer months. Algae might be present in water that is visibly discolored and can include shades of green, blue-green, yellow, brown or red.

To minimize risk to people or pets, State Parks requires that pets be kept on leashes no longer than 10 feet. Other tips include:
