Alberta RCMP have confirmed they were called to two separate, possible drownings Sunday night.
In a news release late Sunday, RCMP said emergency crews were called to the Natures Hideaway Family Campground at around 8 p.m., for reports of a man in his 20s who had disappeared in the Highwood River.
Police said witnesses told them the man jumped into the river from a ledge, surfaced briefly, then went underwater and did not reappear.
Multiple people were said to have gone into the water to try to help the man but were not able to find him.
RCMP, Calgary Police, HAWC and the Foothills Fire Department all searched for the missing man but had to suspend their efforts for the evening.
Crews will return to the area in the morning.
The Natures Hideaway Family Campground is 21 kilometres east of DeWinton and 48 kilometres southeast of Calgary.
RCMP also confirmed they were called to a second possible drowning incident near Lake Louise at around 7:17 p.m. Sunday.
Officials said two people were on paddle boards in Lake Herbert when a man in his early 20s reportedly fell off his board into the water and did not resurface.
According to a release late Sunday, RCMP and Lake Louise Emergency Services searched the lake for the man but were not able to find him.
The search was suspended for the evening and crews will return to the area in the morning.
Lake Herbert is seven kilometres north of Lake Louise and 187 kilometres northwest of Calgary.
