Now, let's take a look at historic flood data in order to determine how frequent and destructive past floods were:

Table 1 -- Historic Floods of Manitou Springs. Adapted from Manitou Springs Flood Hazard Mitigation Plan, Eve Gruntfest, 1985.
DateDescriptionDateDescription

(1) There are several drainage basins running through Manitou Springs. Based on land use, history, and basin size, which drainage has the greatest catastrophic potential?

(2) Which creek floods most frequently?

(3) Using this floodplain map, identify the areas affected by past floods. Do they fall within the 100-yr. or 500-yr. flood zones?

Now that you are aware of the destructive potential of flash floods, please continue to the virtual field study.
