This year’s wet spring sent as much water down the Platte River in two months as usually passes through in an average year.

In September 2013, it began to rain in Colorado. And it didn’t stop. Northwest of Fort Collins, the North Fork of the Cache La Poudre River soon carried record amounts of water. In just a few days, flows leapt from three cubic feet per second (cfs) to more than 1000 cfs when the upstream dam could not hold any more water and began to spill over.
