The Red River is approaching record flood levels, likely to break century-old records this weekend. Flowing north toward Manitoba along the Minnesota-North Dakota border, the river is jammed up by ice and is being fed by rain, snow and meltwater. The National Weather Service has issued projections of a crest of 43 feet near Fargo, North Dakota, 24 feet above flood stage. Volunteers and national guardsmen are out in force, building levees, rescuing and evacuating those that need to get to higher ground. Cold temperatures are hampering efforts, freezing damp sandbags and making the job that much more strenuous for volunteers. 800 more National Guard troops and 150 Red Cross personnel are arriving in the area this weekend.
