Elevation- the amount of oxygen in elevation increases. Since streams get much of their oxygen from the atmosphere, streams at higher elevations will generally have less oxygen.

Salinity (saltiness)- Salty water holds less oxygen than fresh water. Temperature- cold water holds more dissolved oxygen than warm water.
