Overheated planet update: Minnesota now so hot that only some lakes may still be ice-covered for the mid-May fishing opener

Most, if not all, of Minnesota's lakes should be ice free by opener | StarTribune.com

Nearly all lakes in Minnesota should be ice-free in time for Saturday’s fishing opener.
... the State Climatology Office still lists a few northeast lakes, including Brule, Devil Track, Sawbill and East Bearskin, as ice-covered.
“Some of the smaller trout lakes could still have some ice on them,’’ come Saturday, Steve Persons, DNR area fisheries supervisor, said Thursday. But he said recent sun and warm temperatures should help melt what ice is left.

“Anytime ice-out is running this late, we brace ourselves for slow walleye fishing,’’ he said. “The fish won’t be as active.’’ He suggested that anglers heading to his region might consider fishing for trout, or even northerns.

Meanwhile, the DNR warned anglers to beware of the cold water they almost always face on the opener. Water temperatures could hover in the low 50s, or below, in some areas. A 2007 report by the U.S. Coast Guard says a boating accident is five times more likely to be fatal if the water is colder than 60 degrees.
