WILLMAR — A 51-year-old man from Franklin was taken to Rice Memorial Hospital early Sunday in Willmar with non-life-threatening injuries after the sailboat he was on capsized on Big Kandiyohi Lake due to winds from a thunderstorm, the Kandiyohi County Sheriff's Office said in a news release.

The 51-year-old, and a second passenger on the boat, a 48-year-old man from Franklin, were able to swim to the lake's north shore, about a mile away from where the boat was located on the lake. The 48-year-old was not injured and refused medical care.

The identities of the men were not released by the Sheriff's Office.

According to the news release, county dispatch received a call at approximately 1:23 a.m. Sunday about a possible overturned sailboat. The male occupants had been sleeping on the boat, which had been anchored out from the island on the lake. Due to the winds from a thunderstorm moving through, the sailboat overturned and both men entered the water from underneath the boat, the release said. The two men were separated.

The 48-year-old swam to shore and summoned help from the other man's brother. They called 911 and then took a pontoon back on the lake to look for the other man.

The 51-year-old was also able to reach the lake's north shore and find help at a residence on the lake.

Assisting the Sheriff's Office were the Kandiyohi County Rescue Squad, Willmar Ambulance, Lake Lillian Fire and Ambulance and Blomkest Fire Department.
