Factors that impact the temperature of the stream include precipitation, ambient <br />temperature and inputs from storm sewers. The amount of dissolved oxygen available in <br />the water for use in respiration by the stream biota can vary greatly with changes in <br />temperature. <br /> <br />3 <br />
