The magic temperatures range is at least 42 to 44 F 6 to 7 C.

Rainbow trout spawning water temperature.

45F Optimal temperature for Chironomid hatches. There is a possibility of finding some rainbow trout in water bodies having temperatures between 20-23 C depending on the month and period in terms of spawning. Optimum water temperature during incubation ranges from 7 to 12C.

Spawning times can be quite variable and are dependent on water temperaturethey can spawn as early as January in warm areas such as California or as late as June in colder areas. 2015-12-11 Brown Trout spawn in October to November triggered by cooling temperatures and the eggs incubate during the cold winter months to emerge in early spring.

Alternatively Rainbows spawn in April to June triggered by warming temperatures so their eggs cannot tolerate the cold winter water temperatures that Browns endure. 2014-10-29 46F Optimal Brown trout spawning temperature. 2018-08-27 The optimal feeding and movement water temperatures for them is 44 to 67 degrees.
