Rowan, now three, collected a meritorious award from Lothian and Borders Police.
Presenting the award at a ceremony in Edinburgh, a force spokeswoman said: "The officer involved was taken aback by Rowan's amazing actions and there's no knowing what might have happened had she not made that emergency call.
"Rowan's a credit to her family and we're pleased to honour her."
The young girl's father, Robert, later spoke of his pride. Father-of-two Mr Rychel, a 36-year-old network administrator, added: "I'm really proud, really chuffed for her. She's always been really bright since she was very young. We told her at the time she'd been very clever and she was a good girl."
The police force also recognised the courageous acts of 34 others at the ceremony at their headquarters, including a group involved in the rescue of teenager Katie-Lou MacLean from the harbour at Eyemouth last June.
