Retrieval plans are being worked on to get a car out of the Michigamme Reservoir.
According to the Iron County Sheriff's Department, a Crystal Falls man drove his vehicle onto the ice this past Sunday.
The vehicle went through the ice near Sand Island.
The driver and three passengers all got out, but they did lose a dog in the sinking truck.
Authorities want to remind people that ice conditions remain variable, and anyone venturing out should use extreme caution.
