After a two-day, sunrise-to-sunset search, Parks Canada will scale back their recovery operation for a missing 11-year-old Calgary boy who fell into the Yoho River Friday night.

In a release Sunday night, Parks Canada spokesperson Tania Peters said, “Parks Canada will continue to regularly monitor the area in the coming weeks as water levels change with the objective of successfully locating the boy.“ Officials were first notified Friday night that there was a missing boy in the Takakkaw Falls area of Yoho National Park. Friends and family have since identified the 11-year-old as ‘Bezahd.’

According to Parks Canada, two boys were part of an extended family and had been playing by the edge of the Yoho River around 7:40 p.m. July 22 when they both fell in the water.

One boy was able to be pulled from the fast-moving river. The other was not. Parks officials searched for the missing boy until nightfall on Friday night, and resumed their efforts Saturday and Sunday at first light, until it was too dark to continue searching.

The extensive aerial and ground search included a dog handler, as well as local fire, RCMP, EMS, search and rescue crews and two helicopters.

On Saturday Peters confirmed this was being treated as a missing persons case managed by the RCMP, and the thoughts of all Parks Canada personnel are with the boy’s family and friends.

Yoho National Park is about 200 kilometres west of Calgary and approximately 30 kilometres northwest of Lake Louise.

On Saturday Peters confirmed water levels have been high and the rivers flowing fast, but as of 11:50 p.m. Sunday, no streamflow advisories were in place for the area.
