Oxygen best dissolves at surfaces. So generally, you would find the largest amount of dissolved water at the surface, which is in contact with the air. As for a region, I would assume a region that has a lot of photosynthetic organisms and not a lot of oxygen consumers. Another factor that should be kept in mind, is that the lower the concentration of solutes (i.e.. salt) in the water, the more oxygen can be dissolved. For example, at 10 degrees Celsius, up to 8.02mL of oxygen can be present per liter of freshwater, but only 6.75mL of oxygen is dissolved per liter of saltwater. ______________ In polar regions.

Dissolved oxygen refers to the amount of oxygen present in water. It is essential for aquatic life to breathe and thrive. Factors such as temperature, water flow, and levels of organic matter can impact the amount of dissolved oxygen in water.
The level of dissolved oxygen in water can decrease after sunset due to the lack of photosynthesis by aquatic plants. Without sunlight, plants stop producing oxygen through photosynthesis, while organisms in the water continue to consume oxygen through respiration, leading to a decrease in dissolved oxygen levels.

In plasma, the quantity of oxygen in solution is small compared to the amount of oxygen carried by hemoglobin in red blood cells. The majority of oxygen in the blood is transported by binding to hemoglobin, with only a small fraction dissolved in plasma.
Water pollution is not directly connected to oxygenation levels, however, certain types of pollution can result in low oxygen levels. Phosphate runoff leads to excessive growth of algae which then leads to excessive amounts of decaying algae which depletes the water of oxygen. But many types of water pollution have no effect on the amount of oxygen dissolved in the water.

You would expect to find the largest amounts of dissolved oxygen in the surface layer of the ocean, particularly in regions with high levels of phytoplankton and strong wave action which help to oxygenate the surface waters.
In the polar regions, there is more dissolved oxygen in the ocean water. The cold water is able to hold more dissolved gases than warm water.

I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
dissolved oxygen is dissolved oxygen
The oxygen dissolved in water is a measure of dissolved oxygen (DO).
Dissolved oxygen is the current amount of oxygen in the water. A certain amount of Dissolved Oxygen Is needed to keep the fish alive, if any of the dissolved oxygen decreases by either a little or a lot it can cause changes in the water, normally if the dissolved oxygen decreases so do the fish and aquatics life's life.

Nutrients in lakes can cause eutrophication. What happens is that the nutrients cause the algae to grow excessively. As it dies, bacteria consume it using up large amounts of oxygen dissolved in the water. Aquatic creatures that rely on dissolved oxygen (fish) die.
