As a weather geek I will say you will never see flooding like we saw last year. It was the perfect storm with snow depth, frozen ground, warm temps, high winds, and inches of rainfall on top of that. As for the dam, I've been saying for decades that instead of rebuilding after ever major flood since 93 that they should build a reservoir instead of paying out billions every time. My thought was more about the Missouri near Rulo to act as another flood control lake much like what South Dakota has. As someone who has a place at Lake McConaughy, I'd love a big lake in Eastern Nebraska too seeing what it would bring to the economy. Interstates could be rerouted to on top of the ridges and those with million dollar homes by Ashland on the sand pits could be guaranteed prime lots ($200-250k lots) on the new lake and throw them money of top of it to build too. Get r done.
