The solubility of oxygen and other gases depends on water temperature. The colder the water, the more gases it can hold.
Boiling water removes all gases.
Table 5 shows this effect for oxygen in typical lake water temperatures. Oxygen solubility at different temperatures. Temperature Oxygen solubility Deg. The values in Table 5 are found in lakes where continuous mixing occurs, allowing free oxygen exchange between water and the atmosphere. However, the levels often differ greatly from the values found in Table 5 because mixing is seldom complete.
