No progress was made Thursday in the search for two fishermen who have been missing since Monday on Lower Red Lake in northern Minnesota.

Ground and air searches continued for Deland Beaulieu, 29, and a 17-year-old boy whose name has not been released, but efforts were hampered by high winds and below-freezing temperatures.

The Red Lake Department of Public Safety said Wednesday that it would halt water searches because the lake has started to freeze over.

Police on the Red Lake Nation Indian Reservation received a report shortly before 3:45 p.m. Monday that a Red Lake Fisheries boat was having problems on the east side of the lake. The boat capsized and one of the three fishermen aboard was able to swim to shore. He was treated for hypothermia.

Authorities were asking for volunteers from the reservation, and the Tribal Council granted leave to any employees who wanted to help with the search. A Facebook post said authorities expect to use aircraft, drones and cadaver dogs in upcoming searches and will continue to seek the public’s help as needed.

The Leech Lake Tribal Police Department, the U.S. Border Patrol, the FBI, Beltrami County Sheriff’s Office, Bemidji Fire Department and the Leech Lake Conservation Enforcement Department are helping with the search.
