Anyone crossing the Arkansas River south of Great Bend now will see a lot of water flowing where there is usually just a trickle. But, despite the recent deluge, the river will crest at 9.7 feet Thursday which is below flood stage, Barton County Emergency Management Director Amy Miller said.
According to the National Weather Service’s Great Bend river gauge, the Ark will hit this maximum at about midday Thursday. This is just under the 10-foot mark, and anywhere between the 10- and 12-foot stage are considered “action” stages by the NWS.
However, “minor” flooding can occur between 12 and 16 feet, the NWS notes. Between 16 and 18 feet is considered “moderate,” and 18 and over is categorized as “major.”
In the days leading up to Tuesday, the river ran at stage one, with less than 1,000 cubic feet of water flow (water flow is measured in thousands of cubic feet per second, or kcfs). By comparison, by the time it hits the crest, the Ark will flow at about 4.5 kcfs.
After hitting its peak, the NWS expects the river to drop to stage seven (about two kcfs) by Sunday morning.
As points of reference, the NWS lists top river crests at Great Bend.
