Water is in no way disappearing in the place where I'm from, yet there are media and political campaigns about coming water shortages there.
Depending on where you are, there is likely a delta between how much water is typically used and how much is being replenished in reservoirs. So while it's not going to immediately disappear, the rate of replacement is likely lower and unsustainable over a given period of time without corrective action.
One aspect to consider is that abnormal climate events are now harder to predict because shifts in decades (in some cases, centuries) of stable weather patterns. So extreme rains and snows are a good example where models show a trend towards loss of reservoirs, but one event can throw the model off. A good example is the recent snowfalls in Big Sur[0] and then heavy flooding events the following spring [1]

If your part of the world is constantly under drought advisories, I would suggest that rather than going by your "gut" or going by news media, go to the source and find the academic and scientific papers relevant to your region of the world and see why some scientists might be raising the alarm about water levels. More than likely, you'll find that there's solid evidence that the rate of fresh water replenishment is in a negative trajectory.
