Searchers trying to find a man missing in Sikome Lake since Monday discovered a body in the water just before noon on Wednesday.

Alberta Parks says it was able to pinpoint the location of a body in the southeast Calgary lake by using a police helicopter and boat sonar.

Officials believe it is Ali Shaikh, 29, who has not been seen since he fell in the water from a dinghy on Monday afternoon along with two other adults and a baby, who were rescued by witnesses.​  ​  

Shaikh was on a raft with his wife, their nine-month-old child, as well as two adult relatives and another young child.

None of them were wearing life-jackets, but the lake is quite shallow — usually about two metres deep.

The Shaikh family arrived at the lake shortly after the discovery along with the medical examiner and police officers.

After two days of searching with divers and a HAWCS helicopter, the Calgary Fire Department’s aquatic rescue team handed over responsibility of the operation to Alberta Parks on Tuesday — since the lake is within Fish Creek Provincial Park.

Before the body was found, officials said they were examining the possibility of draining the lake to find the missing man. 

"It would take about five days to drain. To refill, it will take about two to three weeks," said Alberta Parks spokesperson Jill Sawyer.

She says the lake will be closed until further notice.

"Our goal will be to reopen it before the end of the summer. Certainly we'll have to test the water quality, as we do all the time, and we'll be advising the public on when Sikome will be open again," she said.

Sawyer says free life-jackets are available at Sikome and other popular provincial parks, but the province is thinking about expanding the program.
