The Colorado Division of Water Resources has many gauges along the South Platte.  On September 18, 2013 their measuring instruments said the water was flowing at 17,000 cubic feet a second under the bridge at Atwood.  (For comparison, on September 18 of 2016 it was running at 153 cfs. The earlier figure was probably suspect as the configurations for those gauges have to be re-set frequently, and some of the equipment had been washed out.Downstream Platte at Atwood Bridge (Near 17,000 cfs) (9-18-13)

Water flowed under and around the bridge and over the roads on either side.Breadth of Platte at Atwood Bridge (9-18-13)

Same as the above picture, just 27 days later.  Water running at 288 cfs.Upstream Platte at Atwood Bridge (288 cfs) (10-15-13)

To point up the irregularity of the river, here is a shot taken October 10, 2010.  This was the only flowing water (There may have been irrigation ditches flowing on either side of the river.) and turkeys were WALKING across it.Turkeys Crossing only channel of River (10-20-10)

During the 2013 flood, these ladies from the United States Geodetic Survey were measuring the South Platte at the Sterling bridges.  Measurements must be made frequently as the depth and width of the river changes constantly as well as the speed of the water flow.USGS Measuring S.

Even when it isn’t “flooding” it can look like it.  Here is a view from the Ford Bridge (Near where Cedar Creek flows into the Platte.) on June 10, 2014.Lake Platte (6-10-14 at Ford Bridge)

This little “sort of flood” took out County Roads 34 and 36 near the river in Logan County, as well as others. The problem was that the river decided to make two or three new channels to the west of the river.County Road 34 to the River (now a channel) (6-30-15) (1st New Channel)
