Significant rain fell across northeastern Colorado between September 9-16, 2013 (image to left shows totals). This rain fell over the headwaters of the South Platte River Basin near Boulder, Colorado. As a result, record flooding occurred in Colorado and western Nebraska along the South Platte and Platte river. Between September 21-28, 2013, minor flooding worked eastward into roughly the western half of the NWS Hastings coverage area, and even lingered into early October in a few places.

The following link from NWS Boulder, CO describes in more detail the event that
resulted in this record rainfall in Colorado:

Below is more information about the basin that feeds into South Platte River, which meets up with the North Platte River just east of North Platte, Nebraska, then becoming the Platte River through the remainder of Nebraska.

Then follows information about each of the river gages along the Platte that affect South Central Nebraska, located near Cozad and Overton in Dawson County, Kearney in Buffalo County and Grand Island in Hall County. A hydrograph showing the rise and fall of each gage as the water passed is shown, as well as "before and after" photos.
