The Corps of Engineers offers some figures showing why the Missouri River is flooding and is likely to stay at flood stage and above for most of the summer. The chief of the Corps of Engineers district water management division, Jody Farhat, says rainfall and mountain snowmelt have put unprecedented amounts of water into the Missouri River basin…
Sioux City, Iowa is the first lage city below the six upstream reservoirs. She says May also went into the record books and has helped produce another record.
Combine the last two months of water flowing into the reservoirs:
One acre-foot of water is the equivalent of almost 327-thousand gallons. Earlier, Farhat said the Corps had been holding back a record 72.4 million acre feet of water–enough to put Missouri and Tennessee, assuming both states were flat, under one foot of water.
Farhat expects water pouring into the lower Missouri from upstream dams will keep levels all the way to St. Louis above flood stage into August.
