The Corps would be heavily criticized for dropping the lake before a storm, as rainfall amounts are highly unpredictable in NWA, and the lake could get very low by the end of a summer. For example: Four inches of rain was predicted for the past four days, and I gauged a half inch or so at my place.
What I was saying is they did not have to release 80,000 cfs or so for five hours in 2008. They then reduced it after the damage was done and someone grasped some sense. They could have released the same total amount over two or three days. Someone at the Corps office likely over reacted and in a knee jerk, they opened the gates nearly full and flooded and scoured everything down Past Houseman. This was 2008. Not even a 100 yr flood, but the lake was already high. On April 24, 2004 there was a 130 year flood on the upper white. 140,000 cfs at Wyman Bridge. Water lapping at the bottom of 45 Bridge. I was there at both sites when it happened. The road washed partly out on the east end at Wyman. The bridge was nearly new. The flood gates at Beaver were not opened excessively and all was fine.
Btw, the floods of 2008 and 2011 on the upper white each registered about 53,000 cfs peak at Wyman Bridge.
