Now in 2009 the Mississippi River freezes north of Iowa, and south of Iowa there are patches of freezing. Around 1900 in St. Louis the river froze which surprised most there although it was really an ice dam of millions of icebergs, and people walked across this "ice gorge" of ice jams. The Corp of Engineers closes for the winter locks from Mid-Iowa north (St. Paul engineering district), although the open locks in mid-Iowa (Rock Island engineering district) and further south are not used much and often they close for a month or so for maintenance. Lake Superior near Duluth use to always freeze but from 1980 onwards there is not even enough freezing to let you walk out and ice fish. Winters in the Midwest are simply milder now. As said rivers are often dammed and made deeper so store more heat, and locks and power plants especially nuclear plants often keep dozens of miles of river from freezing (e.g., Red Wing in Minnesota stays unfrozen due to Treasure Island nuclear plant 10 miles upstream). In the east freezing rivers would clod with ice and flood many towns, which is something authorities now watch for and blast or use icebreakers against. The Red River in Minnesota and Canada every dozen years freezes and then thaws unevenly causing floods unless towns build dikes or huge diversion dams like at Winnipeg in Canada.
