Note that the units are in milligrams per liter, and that the chart is assuming pure oxygen. Atmospheric pressure is 1 bar (at sea level), but the oxygen partial pressure is just 1/5 of that, so the solubility is 1/5th the number at 1 bar.

Assuming you have a 1000 gallon freshwater pond (salt reduces the solubility), at 32F, you could have as much as 0.27 cubic feet of dissolved oxygen. At 68F that number drops to a whopping 0.17 cubic feet dissolved in that entire 1000 gallons.
