Local Flood Hazard Information
The Mississippi River, the Rock River, and their
tributaries are sources of flooding in Moline. The
Mississippi River is the largest river in North America
and forms the boundary between the Iowa and Illinois
Quad Cities. On July 9, 1993 the Mississippi rose to a
record 22.63 feet in Moline, 7.63 feet above flood
stage. This is often considered the base flood (1%
annual chance or “100-year” flood). The Rock River
is a tributary of the Mississippi River and traverses
the southern half of Moline. On March 6, 2008 the Rock
rose to a record 16.33 feet, 4.33 feet above flood
stage. This flood was reportedly caused by rapid snow
melt and also an ice jam near Vandruff Island. Ice jams
are common on the Rock River which can result in rapid,
frequent flooding.
Many properties and neighborhoods in the vicinity of these
rivers or tributaries are located in Special Flood
Hazard Areas. The City of Moline is working to reduce the risk of
personal injury and property damage due to flooding.
Local maps, regulations, and other useful information are available by

The City can determine if your property falls within a
Special Flood Hazard Area and can provide additional
flood documentation upon request. Questions about
local flood hazards, floodplain mapping, construction
regulations, and similar inquiries may be directed to
