Ontario’s Water Quality objective for effluent temperature is out of date and ineffective. Other jurisdictions protect Brook Trout with specific temperature limits. Why can’t Ontario do the same?
As Goes the Air Goes the Effluent
Effluent temperatures is influenced by air temperatures. As the air temperature increases effluent temperature increases. The hottest effluent temperatures occur after consecutive hot days.
