One rainy year doesn't replenish levels (or aquifers). This is a decade's long problem.

- Retric 4y agoA single extreme weather event can refill most dams, what the parent post is missing is it’s actually been a dry year for the watershed and most of the region. https://droughtmonitor.unl.edu/ https://droughtmonitor.unl.edu/ A few areas have gotten normal amount of snow or rain, but watersheds are huge and water is saved up over long timeframes. https://www.usbr.gov/lc/images/maps/CRBSmap.jpg https://www.usbr.gov/lc/images/maps/CRBSmap.jpg
- Retric 4y agoFor those who doubt the mention of a refill from a single weather event, 500 year floods are a thing. It’s more likely the lower the average annual rainfall in a region is, but you get nonliner amounts of flooding with extreme events because a lower percentage is obsorbed into the soil. Large floods can carry more water than the river carries in an average year.
