Mississippi is a yearly occurrence in Adams County.
With the current levee system in place, most
years the flooding does little, if any, damage.
There have been some major floods on record:
1903, 1909, 1912, 1913, 1944, 1960, 1965, 1973, 1985,
and the great floods of 1993 & 2008.
The flood of 1965 broke through the levees
and flooded the river bottoms.
The flood of 1973 reached record levels but the
levees held on the Illinois side of the river.
The floodwaters broke through on the Missouri
side inundating West Quincy, Missouri.
The great flood of 1993 caused major damage
throughout the county. The Mississippi River reached
flood stage on April 1, 1993 and remained above flood
stage until September 4, 1993.
It reached its peak at Quincy on July 13, 1993.
Over $9,355,000 in damages was claimed by public
entities within the county.
FEMA and IEMA covered 90% of the damages in this
disaster or $8,419,538. This still left the county to
pay for the remaining 10% or $935,500.
