The pig was sent packing in Saskatoon with a tracking device.
It's hoped that the data will help the RCMP's historical case unit better understand how fast and far a body travels before it comes to rest.
Cpl. Tyler Hadland says Mounties expect to recover the brightly coloured orange pig during the summer.
Police also sent a pig down the North Saskatchewan River in North Battleford last fall.
It only got about 20 kilometres downstream before it got snagged.
Hadland says Saskatoon's 82-kilogram porker should make it further.
"It's really conceivable that it will travel a further distance ... flow rates this year are a lot higher ... so that is going to be a contributing factor," he said Wednesday when the pig was launched from the Saskatoon Racing and Canoe Club site.
A pig is a good animal to use for the experiment, Hadland added.
"It doesn't have very much hair or fur or anything that may contribute or factor into where it gets hung up."
