Spring Distribution Map (Missouri)

Click image to enlarge


The large springs of Missouri all occur south of the Missouri River, and mostly along the river valleys throughout the Ozark Uplift. Major river basins which are home to large springs are those of the Osage, Gasconade, Meramec, Black, Current, Eleven Point, and North Fork Rivers. Missouri springs are somewhat unique since they occur mainly in dolomite, not limestone--we have the largest number of large springs in dolomite anywhere in the United States.
