Our transcription: Although emergency repair work to strengthen the Low Sill Structure began immediately, it was obvious that more control was needed. At an additional cost of almost $300 million, the Army Corps proceeded with the construction of another control structure and accompanying channel. We learned that we would basically not be able to control the flows unless we did construct another Structure. The Low Sill was just too damaged. The Corps was authorized in the late 70's to build the Auxiliary Structure. The Auxiliary Structure, which was completed in 1986, basically is what its name says -- it's an auxiliary. It serves to complement the Low Sill Structure, allows us to get a better control of the flows. So that in the event that we have a 1973 flood, which was just a tremendous amount of water, that we would not get ourselves in a situation that we did where we almost lost the River.
