DELAFIELD, Wis. (CBS 58) -- First responders rescued a person from Nagawicka Lake Tuesday, Dec. 6, after a witness reported a person in the water. 

Lake Country Fire and Rescue crews arrived at 3:48 p.m. and found the individual 200-feet from shore, attempting to hold onto a floating boat. 

Crews deployed a rescue swimmer wearing a cold-water exposure suit and rescued the individual, transferring them to paramedics nearby. 

The patient was taken to an area hospital with hypothermia and for medical evaluation. 

Lake Country Fire and Rescue wishes to remind the public that while ice has not yet formed on larger lakes, the water temperature will cause "immediate hypothermia" to anyone who is exposed to it. 

They say to always wear a personal flotation device when near the water, have a partner, and never enter the water without proper thermal protection.
