According to RCMP, emergency crews from Lomond and Champion were dispatched to the area at around 1 p.m. on Sunday for reports two males had fallen through the ice while fishing.
The two were fishing together when one went through the ice. When his partner tried to rescue him, he fell through the ice as well.
A third man fishing nearby threw them a rope and managed to pull one fisherman from the icy water, but they were unable to reach the second man who had fallen in.
The man was rescued from the water by the Champion Fire Department and brought to shore where paramedics tried to revive him.
“The male was transported to a local hospital but he did not survive the incident,” RCMP said in a news release.
Little Bow Provincial Park is located 170 kilometers southeast of Calgary.
