1.168mg/L

That's 2.3× as rich as a dead zone, while stressed water is 2.6× higher. That is too little for most fish to survive.

What it means

How much oxygen is in there?

Saturation values are for fresh water at sea level. Seawater holds about 20% less, and altitude lowers it further.

The math

How to convert % to mg/L

Saturation depends steeply on temperature: % = mg/L ÷ saturation × 100, where saturation is 14.6 mg/L at 0 °C and 7.6 at 30 °C. The figures below use the temperature selected above.

Example: 8 % = 1.168 mg/L.

The table below is for water at 0 °C, saturation 14.6 mg/L.
