Since Wednesday, August 14, seven ducks and one heron have been found dead at the pond in Tomlinson Park.
One deceased duck is being tested by the Florida Fish & Wildlife Conservation Commission in Kissimmee. O'Reilly said officials believe a bacterial based infection could be causing the deaths, but officials won't know for sure until all the tests are complete.
The Florida Department of Environmental Protection is also testing the water, according to city leaders.
“We’ve been on this since the first notification. We're waiting for that additional information," O'Reilly said.
City Manager Jim O'Reilly says weed control was conducted on the baseball field on August 7 and the spray and treatment of water lilies in the pond took place early last week.
O'Reilly gave councilors and community members an update about the situation during Tuesday night's regular council meeting.
