The view from Norman County

This is a common sight now. Rural farmhouses formerly surrounded by fields of snowdrifts are losing ground to an expanding lakeshore. It shouldn't be surprising or alarming. Migrating waterfowl have been using these "prairie potholes" for millennia. March has welcomed geese, ducks, and even swans to these temporary, cool pools. If tradition holds, the elegant and ancient cranes will arrive in April. It will be wet for awhile. All we can do is enjoy the view.

The winter that won't end

Our little river was rising significantly and turning into a big river until...until the cold March storm hit. It started as rain and thunder, transitioned to ice and then snow. Now the river is resting again, asleep until winter's claw releases control of the season. But the basement of our house continues to seep. I think the soil is well on its way to thawing out, even if above ground winter has the day.

The landscape is quiet

The wheel of time is creaking slowly on a frozen axis. Puddles form in the fields and ditches. Bare patches of grass are revealed on south-facing slopes. Tributaries are rising slowly. The day-melt and night-freeze cycle is good for sap flow in the trees and for moderating flood potential. But it is now spring and the seasonal precipitation is the final determining factor for the flood equation of 2011. As of today, it remains unsolved.

The plain and simple facts

The floodplain belongs to the river. We can delineate it, map it, drain it, and dredge it. But we can no more do away with a floodplain than we can do away with gravity itself. Would a man sitting in a bathtub expect never to get wet?

We have altered the landscape to such a degree that predicting the severity of flooding from year to year is extremely difficult. Distant records are of little use; the land today does not resemble the land back then.

There will be a flood in the spring of 2011. But we are merely spectators, with a front row seat to one of Nature's most powerful Earth-shaping tools.
