===July 1902===
On July 9, 1902, the river flooded near [[Concordia, Kansas]], breaking a dam and re-routing the river by a quarter-mile (about half a kilometer).<ref>''A Proud Past... A Pictorial History of Concordia, Kansas'', by Bell, Rachel Lowrey (1998), Marceline, Missouri: D-Books Publishing.</ref>

===May/June 1935===
The storm of May 31 and June 1, 1935, (called "Nebraska's Deadliest Flood") dumped an average rainfall of {{convert|9|in|mm}} on the river's watershed. This storm was also unique in that it moved in the same direction as the [[drainage basin]]. As a result, the Frenchman, Red Willow, Medicine, Deer, Muddy, and Turkey creeks all reached their flood peaks at the same time as the crest passed on the Republican River.

According to witness accounts, the roar of the water could be heard coming down the Republican Valley {{convert|5|mi|km|0}} away. Many survivors also reported that there were two crests - the water came up on May 28, then receded slightly, but the second crest on June 1 greatly exceeded the first. At one point, the water rose {{convert|6|ft|m}} in 30 minutes and was {{convert|10|to|15|ft|m|0}} higher than the previous record crest. One eyewitness said the water level rose in some places at 10 miles per hour or more.<ref>The Republican River (2018), {{ISBN|978-1-7329009-0-5}} p. 74</ref> Another account states that the Republican rose {{convert|10|ft|m|0}} in 12 minutes in McCook, destroying the structures in its path. Water was {{convert|20|ft|m|0}} deep in some places, and the discharge was {{convert|280000|cuft/s|m3/s}}, more than 320 times the normal flow today.

Estimates show 113 people killed. From 11,400 to 41,500 head of cattle were killed; one report said that carcasses littering the roads made them impassable. A total of  {{convert|341|mi|km}} of highway and 307 bridges were destroyed, and {{convert|74500|acre|km2}} of farmland were inundated.<ref>[http://www.dnr.state.ne.us/floodplain/mitigation/1935flood.html Nebraska State Historical Society] {{Webarchive|url=https://web.archive.org/web/20110716143901/http://www.dnr.state.ne.us/floodplain/mitigation/1935flood.html |date=2011-07-16 }} "Republican Flood of 1935-Nebraska's Deadliest Flood"</ref>
