·        Creek mouths.  There is a constant flow of water here that will have high levels of oxygen.

·        Rivers.  Again, there will be the constant flow of water present in most rivers.

·        Areas of vegetation.  Aquatic plants need a steady supply of oxygen to keep them alive and thriving.

·        In deep water.  Deeper water is usually colder than higher water.  Therefore there will be a better supply of oxygen.

·        Near power plants.  There will be a continuous discharge of oxygenic water near power plants.

·        Near tree and log areas.  Oxygen is present in treed areas because porous wood will hold oxygen.
