What’s important to understand is water resources are averaged over a multi year period and a few months of normal rain isn’t enough to make things ok.
That said, much of the midwest’s water issues come from assumptions before wells dropped water levels in the region. A stream can gain or lose water based on the local water table so simply getting X rainfall per year doesn't guarantee a dam will continue receiving the same amount of water year after year. Worse models aren’t based on unlimited data, random events can mean you’re basing things in unusually good times, even ignoring climate change.
