Dumped pets create big problems for Knoxville lake

December 10, 2018

KNOXVILLE, Tenn. (AP) — Workers in Knoxville have removed three truckloads of invasive weeds from a local lake, including aquarium grasses that officials believe were dumped there by residents.

The Knoxville News Sentinel reports the city has spent nearly $760,000 cleaning up the one-acre lake in Fountain City Park.

Efforts to clean the lake have been going on for more than 30 years. First, the feces from abandoned pet ducks created a massive algae problem. Once the algae was under control, the invasive grasses took over.

David Hagerman is a stormwater engineer for the city.

He told the paper that people may intend to give their aquarium inhabitants a chance at life. But he says the reality is the animals have almost no chance of survival and the exotic plants overtake native vegetation.
