Stream water typically has more oxygen because it flows constantly, allowing more oxygen from the air to dissolve into the water. In contrast, pond water is stagnant and can become depleted in oxygen over time due to limited exchange with the atmosphere.
Compared to what? Typically, water at the surface that makes contact with the air would absorb the most oxygen, while water below it would absorb less. Since a fast-moving stream would have lots of turbulence, then it have the water below the surface getting a good chance to change places with the water at the surface ofter, so there would be more water getting to the surface and absorbing oxygen. Also, the fast-moving stream would probably have more air bubbles created, and these bubbles would be in contact with water below the surface and help that water to absorb oxygen stored in the bubble.
Cold water can hold more dissolved oxygen than hot water. This is because the solubility of oxygen in water decreases as the temperature increases. Therefore, cold water has the ability to hold more oxygen than hot water.
Oxygen is generally more soluble in fresh water compared to salt water. This is because the presence of salts in salt water reduces the solubility of gases like oxygen. Additionally, temperature and pressure also play a role in determining the solubility of oxygen in water.
Flowing water generally has more dissolved oxygen than still water because moving water allows more oxygen to be absorbed from the air. Still water can become depleted of oxygen over time due to lack of replenishment, especially in stagnant or enclosed areas.
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
there is more dissolved oxygen present in a stream because the movement and the bubbling of the air allows more oxygen to be ingested
Fast moving stream
Which is more salty water stream or lake van
No. There is more oxygen in deeper water.
Freshwater has more oxygen than salt water but oxygen is more solublein fresh water.
Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.

It means the stream is getting more water.
Biochemical Oxygen Demand is the measure of the amount of oygen consumed by microorganisms in decomposing organic mattter in water bodies. BOD directly affects the amount of dissolved oxygen in water-bodies (i.e. rivers and streams). The greater the BOD, the more rapidly oxygen is depleted in the stream. SOURCE: Google.
