Gavin's releases approach 140 kcfs, new levees being tested

 As flows from Gavin's Point Dam approach 140 kcfs (thousand cubic feet per second), new levees and sandbag structures are being tested throughout South Dakota, Iowa and Nebraska. In addition to flooding of riverside homes and businesses, utilities and infrastructure are being tested in many communities. From water supplies, wastewater plants and train routes to interstate closures and electric plants, eyes are watching the rising floodwaters and the effects it will have on commerce and basic services. See below for frightening video of the Fort Calhoun Nuclear Plant, which is already surrounded by water.


Lower on the river, Missouri communities are attempting to prepare for predicted high flows which, because of relatively dry weather and low flowing tributaries, have not yet manifested. Rain is currently falling in Nebraska, Iowa and northwestern Missouri, heightening the chances for increased tributary flow.

Perspectives
A few editorials regarding the flood
Bismarck Tribune, June 9, 2011 - "Time to revive Mo River study?" - Brian Gehring

St. Louis Post Dispatch, June 7, 2011 - "Guest Commentary: The looming Missouri River dam flood" - Bernard Shanks
This is a frightening warning about the vulnerability of the dam system (specifically Fort Peck dam in Montana) to unprecedented reservoir levels and stress. The Corps continues to state that the reservoirs, under constant surveillance, are in good shape and performing as expected. In addition, the liquefaction fear that Shanks reports is mainly due to earthquakes, not water pressure. Still, fear of dam failure is a real concern...just not the most immediate concern to worry about right now. 

Great Plains Examiner, June 9, 2011 - "Without answers from Corps, public blames flood on plovers"
A good look at some of the parameters the Corps is working under. However, the Corps has been explaining the unprecedented nature of the late spring snow pack and May Montana flooding, which is the real cause of the huge runoff numbers. We'd like to see what kind of spring releases would have been required to avoid these current releases - and suspect that there is no realistic scenario that would have avoided this.


Montana
Associated Press, June 8, 2011 - "Montana town floods for second time in 2 weeks"

Officials monitor river speed. Lower speed will mean a delta is forming downstream and river stages will rise.

Several I-29 closures are expected between Missouri border and Sioux City, IA.
