Indian Creek in 42N country flash flooded after 7.07 inches of rain came down on August 27, 2009. Annually the creek floods (usually in late May or June but not always) despite flood control improvements up creek in northern Linn County, Iowa. The protection of the homes in the area above will require more structural improvements to the flood plain including a dike or series of berms plus more aggressive upstream flood controls.On Saturday, August 29th the creek had receded to its banks and left clear indications of the force of the Thursday rising water. Typical of the any flood on this creek are flattened grasses, new sand bar deposits, and uprooted trees. This flash flood was no exception to the pattern. Know that.
