In a body of fresh water, a dissolved oxygen concentration of 0.262 or higher is usually needed to maintain a healthy aquatic ecosystem. For a lake to maintain this concentration, what is the maximum water temperature?

To determine the maximum water temperature for a lake to maintain a dissolved oxygen concentration of 0.262 or higher, you would need to consult a dissolved oxygen solubility chart. This chart provides the relationship between dissolved oxygen concentration and water temperature.
Here are the general steps to find this information:
1. Start by searching for a dissolved oxygen solubility chart specific to freshwater.
2. Locate the dissolved oxygen concentration of 0.262 on the y-axis or chart's scale.
3. Follow the row or line representing this concentration until it intersects with the column or line representing water temperature.
4. Read the value of the water temperature where the intersection occurs.
The specific value obtained from the chart will represent the maximum water temperature at which a dissolved oxygen concentration of 0.262 or higher can be maintained.
