The engineers talk about high water for a long time causing erosion and failure. Ask them if they checked the high water in 2002,2004,and 2008. Same scenario, no failure.
This time gates plugged, capacity of spillway reduced to what?—-20,000cfs–15,000cfs when all the trash smacked into the gates. The capacity of the dam was 32,000cfs. The volume of flow was 24,900cfs. In 2004 the flow was 26,000cfs.
Any one that has “played” water knows that once the outlet route begins being plugged, the result is just a larger restriction of the outlet.
Spillways will erode, leaks will appear, and whirlpools will develop if the outlet is plugged.
Did any one ask why the Lakehurst Dam downstream survived and Lake Delhi didn’t?
Could it be that Lakehurst Dam opened the gates in a timely manner, had crews on site 24/7 to remove debris, and had all the gates open. Both dams are about the same age, but not much older than the dams of the Upper Mississippi. The Lakehurst survived with 65,000cfs passing through it. The largest floods in almost 100 years of reporting were 48,000cfs.
If I am not mistaken, the Lakehurst Dam survived a flood 35% larger than at any previous time.
The Lakehurst Dam took a 69,000cfs surge from Lake Delhi plus the river flows from 1,200 additional square miles of river (Lake Delhi watershed is 347sq./miles).
The operators of Lake Delhi Dam knew or should have known that the dam was in trouble by 6 to 9pm on Friday. At that time a crane should have been dispatched to pull up or rip out the stuck gate. Instead nothing was done until it was too dangerous to be on the dam–twelve hours later.
here we go again! this just goes to prove the DAM WAS NOT maintained like it should have been. look how much it cost the states and etc to maintain dams. how did the delhi assoc. THINK THEY COULD AFFORD to do this on their own?
