Tips for lake ice safety:

Be extremely careful during winter activities that involve Lake Zumbro such as ice fishing, snowmobiling or just walking out on the frozen lake.
Watch the weather and river flow conditions.
Ice thickness and condition can vary greatly. Be very cautious.
Look out for ice heaves and exposed logs and snags.
Be cautious in the vicinity of the dam. De-icing equipment has been installed along the upstream face of the dam resulting in open water and/or thin ice.
