Topeka ? High heat and algae apparently combined to kill up to 1,000 fish at a city park in Topeka.

Park and recreation workers removed the fish Monday from the Central Park Pond in central Topeka.

City spokesman Dave Bevens told WIBW-TV that samples taken from the water indicated that a large algae bloom and last week’s extreme heat cut off oxygen for the fish in the pond. He says no other reasons for the kill were found.

Bevens said city residents should be aware that the bacteria level in the water is likely high, but the city did not issue a “no contact” order for the pond.
