The Rock County Sheriff’s Office is warning anglers to stay off of the ice on Lake Koshkonong.
The Sheriff’s Office says the rescue team was dispatched to help the Jefferson County Sheriff’s Office with a water rescue in the town of Koshkonong Monday morning.
Although the incident was determined to be unfounded, deputies observed a large amount of open water on the lake and found that where ice did exist it was only a few inches thick and unstable.
