IMHO vastly lowered water level exacerbates some of the reasons we use aeration. The evaporation greatly increases the concentration of minerals in the water, some of which tend to be problematic. The reduced volume increases the density of fish biomass, hence increasing the need for oxygen.

I'd be running aeration quite a bit in your circumstances.
