Fish Kills
Fish may die when they are trapped in isolated pools during the summer . As the pools shrink and air temperature increases , the water temperature increases , and oxygen is lost to the atmosphere . Most fish are sensitive to low oxygen levels and extreme fluctuations in water temperatures .
Fish killed by a pollution incident are likely to be found in :
Pools covered with an iridescent sheen or floating debris ,
Pools with an unusual coloration or cloudiness , or
Smelly water from excess algae in the water ( algal blooms ).
Contact City staff if you have identified or suspect pollution in and / or around nearby creeks or storm drains !
Look for additional information on the GETTING HELP page at the end of this handbook .
