Historic Crests

Not many folks live on the west side of I-35 now in the river bottom.
Those that still live there have had to rebuild and now have houses on raised ground. Wife's Uncle has been flooded out totally three times with the house destroyed. I-35 is like a dam. Only three outlets from the Kansas border south to almost Perry.
The Chikaskia River, the Salt fork River, and Black Bear Creek. Billions of gallons of water can't make it through those outlets without flooding during periods of heavy flooding rainfall.
