so warmer raising the water temperature reduces dissolved oxygen? thats a fun fact.

im used to thinking about the opposite, moisture in air :) thermo is fun......
i don't spend much time thinking of oxygen in water. however sense is made

the majority of nuclear plants change the river/stream temperature by small amounts, i believe the laws keep it within a degree or 2
