• 1993 Floods: During the spring floods of 1993, which covered nine Midwest states, a high
percentage of crop acres in the U.S. Army Corps of Engineers KC District floodplain areas
suffered losses because of overtopping of nine of the 15 units in the federally constructed
Missouri River Levee System and virtually all the nonfederal farm levees in the district
Extent
Region L is a highly populated and traveled area within the state which is co-located with the
Missouri and Kansas Rivers. The levees and dams that protect the planning area are critical to
ensuring the safety of the population, property, and infrastructure. The planning committee has
determined that a dam or levee failure would be critical to the Region with 25% - 50% of
property severely damaged, a complete shutdown of critical facilities for at least two weeks, and
injuries or illnesses that could result in permanent disability.
Probability of Future Hazard Events
Dam Failure
Due to the variability of the size and construction of the dams in Kansas, estimating the
probability of dam failure is difficult on any scale greater than a case-by-case basis. The limited
data on previous occurrences indicates that in the last 87 years, there have been 7 recorded
dam failure events in Kansas which is less than 1 event in 10 years. Therefore, this hazard’s
CPRI probability is “Unlikely” (event is possible within the next 10 years)
