Mississippi River/Delta Field TripSept. 28-Oct. 3, 2004: R. Douglas Elmore

A couple of quotes from a wise man.

“The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise...”- Mark Twain in Eruption

“One who knows the Mississippi River, will of her not allow himself, that 10,000 river commissions with the minds of the world at their back cannot curve it or confine it, cannot say to it go there and make it obey, cannot save a shore which has been sentenced, cannot bar its path with an obstruction which is will not tear down, dance over, or laugh at.” Mark Twain

First Day-The long road to Louisiana

The second day-Old River Control

Second Day-Old River Control. The talk on Old River Control by Bill, the hydroelectric plant employee. The side scan sonar map shows the locations of the Low Sill structure, the Auxiliary Structure andHydroelectric plant.

Close up of the side scan sonar map. Note the bedforms in the Mississippi.Also note the deep hole (black oval) to the south of the Low Sill Structure Which was important in the 1973 flood.
