The annual fish kill given in the report represents the combined efforts of private individuals; state fish and game, health, and conservation officers; and water pollution control officials at the state and Federal level. Usually, a fish kill is first noticed by a fisherman, camper, or other private citizen, who informs a warden or other state official. It is essential that a fish kill be reported and investigated immediately in order to determine the source of pollution and the polluting agent. Dead fish may be washed downstream from the source of pollution. The reporting system depends, to a large extent, upon individuals in the field making state officials aware of fish kills.
