In a true sign of spring, the Minnesota Department of Natural Resources has declared official ice-out dates for six lakes in the state. All six lakes are shallow bodies of water in southern Minnesota. They were officially declared ice-free last week. The first was Iowa Lake in Martin County, which saw ice-out on Tuesday. The other five lakes were Hall Lake, Budd Lake, Park Lake, Smith Lake and Lake Shetek. The spring thaw is starting a few weeks later than usual, after a bitterly cold winter.
