In September, 2013, the Big Thompson River flooded, sweeping down its channel from Estes Park to Loveland, Colorado and out onto the plains, overflowing its banks all the way. Small rivers seem placid, even when they are rushing down from the mountains. The power of those same rivers in flood was a revelation to those of us who had not seen it before. The water swept away all the river-side vegetation, leaving naked gravel and all sorts of debris.
I spoke with people--a land owner along the river, a neighbor who regularly walked riverside paths--who wondered whether the riverside would ever recover.
