The hydro plant for my city doesn’t even have a reservoir. It’s just on a river. And 99.999% of the water doesn’t go through any turbines.
Having said that - it doesn’t produce enough power for the city, let alone spare to be wasted on other things.
I'm no fan of Bitcoin, but often the energy they use from hydro plants is energy that would literally be wasted otherwise. A hydro dam can't control how much water is entering the reservoir, so if there's more water entering the reservoir than is needed to generate electricity for the current demand then the dam will need to just throw the extra water away. Trying to transmit the electricty to remote markets can be an alternative, but that costs resources too and isn't always practical.

I dug up the original article: https://www.politico.com/magazine/story/2018/03/09/bitcoin-mining-energy-prices-smalltown-feature-217230/
In this case, they already were exporting 80% of the hydro-energy generated, about enough to power Los Angeles in 2018 when it was written. Maybe there are some cases for your suggestion on a small scale, but if a site is generating enough excess electricity to make mining worthwhile, why would it be less worthwhile to connect it to a larger grid?
