As a result, The Corps of Engineers had to release unprecedented amounts of water starting in May of 2011 and which caused terrible flooding of the Pierre area as well as further downstream. Rick wanted to check this area out in August after over 3 months of water releases.
This looks downstream and you can see the trees are actually in the water. The trees are actually on a large levee which usually is several feet above the water. I would guess that the powerhouse river is at least three times as wide as it usually is.
This gives a better view of the powerhouse and you can just see a platform on the left side of the river that seems to be almost floating. This is actually a fishing pier and is usually about 8 to 10 feet above the water -- now it is literally at the water level.
Wow! Prior to this spring, Oahe had released a maximum of about 55,000 cubic feet per minute of water. This spring, that reached a record 160,000 CFM. Now, this is being reduced, but is still at about 130,000 CFM. This was almost scary to stand next too as the roar was very loud and the ground literally shakes. You can get a good idea as to this in the video below.
