Natural temperature means the temperature which occurs naturally when the water is not influenced by known discharges or activities which may cause an increase or decrease in the temperature in the water.

Natural temperature means the temperature that would exist in waters of the commonwealth without the change of enthalpy of artificial origin, as contrasted with that caused by climatic change or naturally occurring variable temperature associated with riparian vegetation and seasonal changes.

  • Natural temperature changes and ultraviolet light from the sun break residual cyanide and metallo-cyanide complexes down to simpler, less toxic, more stable compounds.

  • Natural temperature is defined as that temperature of a body of water (measured as the arithmetic average over one hour) due solely to natural conditions without the influence of any point-source discharge.

  • Natural temperature variability is a re- quirement for high species richness.

  • Natural temperature variation affects larval survival, development and Hsp70 expression in a leaf beetle.
