A teenage girl from Souris, Man., died in what emergency responders call a tragic, freak accident after she fell into a water tank on a farm west of Brandon on Sunday.

The 14-year-old was walking in a farmyard in the rural municipality of Whitehead at about 3:15 p.m. when she stepped on the lid of the water tank, knocking it off and falling into the water about 20 feet down, RCMP said.

Kelly Crosson, chief of the Whitehead Fire Department, said firefighters arrived at the scene within 10 minutes and pulled the girl out.. They preformed CPR until paramedics from Brandon arrived.

"The outcome was very tragic," Crosson said Monday. "We worked hard to try to get a better result but unfortunately the result wasn't good."

"It was just a freak accident. A trip and fall," he said.

The girl was taken to the Brandon Regional Health Centre, but she was pronounced dead on arrival.

RCMP said the girl lived in Souris, Man., but was visiting a family friend who lived on the farm.

Crosson said the tragedy has shaken members of the fire department. He said the department is lining up critical incident stress management for members who were at the scene on Sunday.

"It takes a while for these [incidents] to sink in," said Crosson.

Crosson said the tragedy should serve as a reminder for parents and property owners to check their properties to make sure wells and septic tanks, a common fixture on farms and rural properties, are properly sealed

"It was a freak accident," he said. "It's something that was preventable."

RCMP said the death is not being investigated as suspicious.
