Medicine Hat to drain Celebration Park pond to remove invasive goldfish

Leaving the pond empty through the winter is considered the most environmentally friendly option to reduce the likelihood of the fish returning when it is refilled in the spring, according to the City.

The approach could also eliminate the need for chemical treatments.

Water drained from the pond will be used to irrigate newly planted trees, while the remaining water will be directed to the south end of the park to prevent pooling around existing infrastructure.

Barricades or fencing will restrict public access during and after the work. Once the pond is drained, the goldfish will be removed and disposed of at the Waste Management Facility.

No outdoor skating surface will be available at Celebration Park this winter while the pond remains empty.

Goldfish can harm aquatic ecosystems by increasing water turbidity and organic matter, reducing oxygen levels and contributing to algae blooms. They can also outcompete other species, creating an imbalance in the ecosystem.

Removing the fish is expected to improve water quality and clarity over time, the City said.

The pond also serves as a water source for irrigation in Celebration Park, making water quality important.

Draining it during the summer was not an option because of its role in supporting irrigation.

No native aquatic species will be affected during the draining and removal process, according to the City.

The situation highlights the environmental and financial consequences of releasing non-native fish into local waterways.

Invasive aquatic species have also affected areas such as the Northlands Storm Pond, where removal efforts have been costly to taxpayers and the environment.

Residents are reminded that releasing non-native fish, whether alive or dead, into local bodies of water is illegal.

Flushing unwanted fish down the toilet is also discouraged.

For those who can no longer care for aquarium or pond fish, the Government of Alberta recommends contacting a pet store, giving the fish to another aquarium or pond owner, donating it to a school or consulting a veterinarian.

The City thanked residents for their understanding while the work is completed.
