"She absolutely loved animals and was showing her parents she could handle the responsibility of a dog by walking a few other dogs in the community."
Last Saturday afternoon, the girls had been taking one such pet for a walk when it suddenly went after a flock of birds and jumped into a drainage pond.
Ms Maksymova, a talented gymnast who was set to compete at national levels in 2018, followed the dog but got stuck and disappeared from view.
Several local residents made attempts to save her, but also found themselves stuck in the mire.
Emergency services arrived shortly before 2pm, and pulled Ms Maksymova from the water.
She was rushed to hospital and put on life support, but died the following day.
On Sunday, the local community held a candle-light vigil for the teenager, with dozens gathering to honor Ms Maksymova's life.
