The MN river from the Cedar Ave boat landing to downtown St. Paul appears to be open. I took a drive yesterday on Water st / Lillydale rd and the Mississippi river seemed quite navigateable. Stopped by the landing under cedar ave bridge (permit required) and took a snap of the landing and one of an adventurous soul already on the water.
BTW the Lillydale boat landing still has 30 feet of ice
Good luck and above all be safe
