Increased flood levels prompted the closure of Interstate 29 once again, from Highway 34 southward to the Missouri Border, and from I680/29 split northward to the I680/80 split. Gavins Point Dam releases were increased from 55,000 cfs to 75,000 cfs by the end of the month.

From 4 to 15 inches of snow cover remained across the mid Missouri River valley, and the ground was frozen with existing frost depths of 15 to 23 inches. Warm temperatures allowed all...
