WINONA — The Winona County Sheriff's Office and Winona Fire Department are searching Lake Winona today for a possible drowning victim. 

Winona County Sheriff Ron Ganrude said dispatch received a call at 10:29 a.m. from a woman who was on the bike path along Lake Winona. The caller said she saw someone in the water struggling.

"We've been trying to find that person since," Ganrude said.

The sighting occurred near the boat ramp near Franklin Street on the north side of the lake, Ganrude said. The woman told dispatchers that she saw someone with their arm up in the water. She looked away for a moment and when she looked back, the person was gone.

The county's dive rescue boat and the city's fire department are on scene as of noon, Ganrude said, and the water patrol was responding. 

As of noon, there were no reports of missing individuals. The sheriff's office was also searching the area for a car or bicycle left unattended. 

While the spot where the swimmer was sighted is not a popular place to swim, Ganrude said people often do swim in Lake Winona. It is also used for kayaking, canoeing and paddle boarding. However, no unattended boats or boards were seen in the water.
