Toxic Algae Blooms That Can Harm Dogs Found In Prospect Park Lake

PROSPECT PARK, BROOKLYN — Toxic algae blooms have appeared on Prospect Park Lake for the fourth year in a row.

Tests carried out by the Department of Environmental Conservation on June 19 showed algae growth across the lake, the agency's website said. The growth is caused by the level of phosphates in water that is being pumped into the lake from the city's supply.

The algae depletes oxygen needed by other plants and wildlife and can produce toxins which are dangerous for people and dogs, according to a spokesman from the Prospect Park Alliance. The alliance has put up signs around the lake warning visitors not to let their pets go in the lake.

The green algae can cause a rash if it gets in contact with skin and can lead to neurological problems if ingested, according to an alliance spokesman.

Symptoms include excessive saliva, breathing problems, dark urine, vomiting, diarrhea and convulsions, according to Pet Poison Hotline.

No signs of algae blooms were detected in the Park’s Upper Pool, where Dog Beach is located, according to officials. The park's water will continue to be tested on a weekly basis.

The Alliance received $390,000 from the State in February to tackle the level of phosphates in the water supply by installing two natural filtration systems, according to the park's website. There is no set timeline for the project to be completed.
