Anything that is dumped in local storm ponds or storm drains will flow directly into our storm water system and into the Red Deer River," said Tim Ainscough, the city's environmental services manager, in a release.

"Removing invasive species will help to ensure that we maintain the aquatic health of our storm water system and local waterways."

Anders Pond will be fenced off from Sept. 9 to Oct. 21, while the city sprays a natural pesticide called Rotenone to kill off the fish and remove their carcasses.

It's toxic to fish species, but low to moderately toxic to birds, mammals, amphibians and inverterbrates.
