A ground team of police officers, marine divers and helicopters are looking for a 73-year-old man ACT man missing in the Snowy Mountains.
The man had gone fishing at Lake Eucambene, near Adaminaby.
He was accompanied by another 73-year-old man, whose body police said they had found on Thursday.
The two fisherman were reported missing about 11.15pm on Wednesday to officers from the Monaro Police District.
An extensive search of the waterways and nearby bushland ensued.
The police search was joined by NSW Marine Area Command divers, NSW SES, Toll Ambulance Rescue Helicopter Service, Westpac helicopter, and Marine Rescue.
After the body of one of the fishermen was found on Thursday, the multi-agency search had to be suspended about 3pm due to bad weather.
Police will continue to look for the second fisherman from 8am on Friday.
"We can say at this stage, [the search teams] are going to make every effort to locate him. The search is ongoing," a spokesperson said.
Owner of Eucumbene and Jindabyne Fishing Charters Mark Fountain said the lake, about a 90-minute drive from the capital, was a popular spot for Canberrans to go fishing.
He said in bad weather the lake would become very rough and had "killed" about 20 people since it was built.
"Small boats, big waves, don't mix," Mr Fountain said.
